22q11 Deletion Syndrome: Condition with a variable constellation of phenotypes due to deletion polymorphisms at chromosome location 22q11. It encompasses several syndromes with overlapping abnormalities including the DIGEORGE SYNDROME, VELOCARDIOFACIAL SYNDROME, and CONOTRUNCAL AMOMALY FACE SYNDROME. In addition, variable developmental problems and schizoid features are also associated with this syndrome. (From BMC Med Genet. 2009 Feb 25;10:16) Not all deletions at 22q11 result in the 22q11deletion syndrome.DiGeorge Syndrome: Congenital syndrome characterized by a wide spectrum of characteristics including the absence of the THYMUS and PARATHYROID GLANDS resulting in T-cell immunodeficiency, HYPOCALCEMIA, defects in the outflow tract of the heart, and craniofacial anomalies.Chromosomes, Human, Pair 22: A specific pair of GROUP G CHROMOSOMES of the human chromosome classification.Syndrome: A characteristic symptom complex.Chromosome Deletion: Actual loss of portion of a chromosome.Velopharyngeal Insufficiency: Failure of the SOFT PALATE to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. Incomplete velopharyngeal closure is primarily related to surgeries (ADENOIDECTOMY; CLEFT PALATE) or an incompetent PALATOPHARYNGEAL SPHINCTER. It is characterized by hypernasal speech.Gene Deletion: A genetic rearrangement through loss of segments of DNA or RNA, bringing sequences which are normally separated into close proximity. This deletion may be detected using cytogenetic techniques and can also be inferred from the phenotype, indicating a deletion at one specific locus.Abnormalities, MultipleCraniofacial Abnormalities: Congenital structural deformities, malformations, or other abnormalities of the cranium and facial bones.Chromosome Disorders: Clinical conditions caused by an abnormal chromosome constitution in which there is extra or missing chromosome material (either a whole chromosome or a chromosome segment). (from Thompson et al., Genetics in Medicine, 5th ed, p429)Sequence Deletion: Deletion of sequences of nucleic acids from the genetic material of an individual.Intellectual Disability: Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range. (from Joynt, Clinical Neurology, 1992, Ch55, p28)Jacobsen Distal 11q Deletion Syndrome: A clinically recognized malformation condition caused by a distal 11q deletion.

Most patients have a THROMBOCYTOPENIA and platelet dysfunction known also as Paris-Trousseau type thrombocytopenia.Hypoparathyroidism: A condition caused by a deficiency of PARATHYROID HORMONE (or PTH). It is characterized by HYPOCALCEMIA and hyperphosphatemia. Hypocalcemia leads to TETANY. The acquired form is due to removal or injuries to the PARATHYROID GLANDS. The congenital form is due to mutations of genes, such as TBX1; (see DIGEORGE SYNDROME); CASR encoding CALCIUM-SENSING RECEPTOR; or PTH encoding parathyroid hormone.Developmental Disabilities: Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders. (From American Psychiatric Glossary, 6th ed)Parietal Bone: One of a pair of irregularly shaped quadrilateral bones situated between the FRONTAL BONE and OCCIPITAL BONE, which together form the sides of the CRANIUM.Cri-du-Chat Syndrome: An infantile syndrome characterized by a cat-like cry, failure to thrive, microcephaly, MENTAL RETARDATION, spastic quadriparesis, micro- and retrognathia, glossoptosis, bilateral epicanthus, hypertelorism, and tiny external genitalia. It is caused by a deletion of the short arm of chromosome 5 (5p-).Phenotype: The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.Hemizygote: An individual having only one allele at a given locus because of the loss of the other allele through a mutation (e.g., CHROMOSOME DELETION).In Situ Hybridization, Fluorescence: A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy.

The genetic abnormality results in a defect in the osteoclastic activity at the metaphyseal ends of the bone during the remodeling process in childhood or early adolescence. The metaphyses develop benign, bony outgrowths often capped by cartilage. A small number undergo neoplastic transformation.Learning Disorders: Conditions characterized by a significant discrepancy between an individual's perceived level of intellect and their ability to acquire new language and other cognitive skills. These disorders may result from organic or psychological conditions.

22q11.2 deletion syndrome is a disorder caused by the deletion of a small piece of chromosome 22. Most people with this disorder are missing a sequence of about 3 million DNA building blocks on chromosome 22 within each cell. This disorder affects many areas of the body. People with 22q11.2 deletion syndrome may have heart defects, immune deficiency, kidney abnormalities, hearing loss, and cleft palate or other facial deformities. Many children experience developmental delays and learning disabilities, and they have an increased risk of developing mental illnesses, including schizophrenia, depression, anxiety, and bipolar disorder. All people with 22q11.2 deletion syndrome are missing the same sequence of DNA, but the severity of this disorder varies widely; some people are diagnosed with multiple health and developmental problems, while others experience very few symptoms. In some people, the symptoms may be so minimal that they are not even aware they have 22q11.2 deletion syndrome. This study ...
Nadia Zomorodian is one of the approximately 2,000-4,000 children born each year with 22q11.2 deletion syndrome. Although it receives less public awareness, it is believed that 22q11.2 deletion syndrome is as common as Down syndrome.From Day One, Nadia was a fighter. She was born with a congenital heart defect, which required surgery when she was only one week old. Nadia was also born with a cleft palate, which made it difficult for her to breathe and swallow properly, and caused her to develop aspiration pneumonia a total of 12 times before she was even two years old. She was in and out of the hospital throughout her infant and toddler years, and at age three was finally given the diagnosis of Velocardiofacial Syndrome, now commonly known as 22q11.2 Deletion Syndrome.. 22q11.2 deletion syndrome is a genetic disorder caused by a deleted or missing section of chromosome 22. The deleted segment is present at the time of conception and in 10% of cases is believed to be inherited from a parent; in ...
Polymicrogyria is a brain malformation due to abnormal cortical organization. Two histological types, unlayered or four-layered can be distinguished. Polymicrogyria is a rare manifestation of chromosome 22q11 deletion syndrome. We report two boys with chromosome 22q11 deletion syndrome and polymicrogyria, and describe the neuropathological features of the malformation in one of them. Clinical examinations, EEG, brain MRI, chromosomal analysis with FISH, and neuropathological studies of surgically resected cortical tissue were performed. Both patients showed severe developmental delay with cardiovascular malformations and one of them had drug resistant epilepsy. Polymicrogyria was found in the frontal, parietal, and temporal areas, unilaterally in one patient and bilaterally in the other. Histology revealed four-layered polymicrogyria. The pathogenesis of polymicrogyria in 22q11 deletion syndrome is discussed.
Most people with 22q11.2 deletion syndrome are missing about 30 to 40 genes. The exact function of many of these genes remains a mystery. But one gene, TBX1, probably accounts for the syndromes most common physical symptoms, including heart problems and cleft palate. Another nearby gene, called COMT, may also help explain the increased risk for behavior problems and mental illness in people with the syndrome.. About 90 percent of 22q11.2 deletion syndrome cases occur randomly at fertilization or early in fetal development. So most people affected with the disorder have no previous family history of it. However, they may pass the condition on to their children. The remaining 10 percent of cases are inherited from either the mother or the father. When the condition is inherited, other family members could also be affected. Because a person who has this chromosome deletion has a 50 percent chance of passing the deletion to a child, both parents are generally offered the opportunity to have their ...
Researchers at the UC Davis MIND Institute will participate in an international consortium spanning four continents that will study the genetics of schizophrenia and other psychiatric disorders in chromosome 22q11.2 deletion syndrome through a four-year, $12 million grant from the National Institute of Mental Health to the International Consortium on Brain and Behavior in 22q11.2 Deletion Syndrome.
Abstract: The COMT gene is thought to contribute to the cognitive/psychiatric phenotypes in 22q11.2 deletion syndrome. We measured these manifestations against the Val/Met alleles of the COMT gene, in 40 nonpsychotic 22q11DS children. The Val allele was associated with poor IQ, processing speed, executive function and a higher frequency of anxiety disorders, underscoring the importance of the COMT gene in the childhood psychopathology in 22q11DS.. COMT and anxiety and cognition in children with chromosome 22q11.2 deletion syndrome ...
Monosomy 1p36 Deletion Syndrome 1p36 deletion syndrome is a chromosome disorder. A chromosome disorder is a change in chromosome number or structure which results in a set of features or symptoms. People with 1p36 deletion syndrome have lost a small but variable amount of genetic material from one of their 46 chromosomes. 1p36 deletion syndrome was described for the first time in the late 1990s, although the first case of a child with a deletion of 1p36 was published in 1981. Most reports suggest that 1p36 deletions affect girls more often than boys - around 65 per cent of reported cases are girls. Unique families support this: 73 per cent of the children with 1p36 deletion syndrome are girls. The reasons for this are, as yet, not known.
The features of this syndrome vary widely, even among members of the same family, and affect many parts of the body. Characteristic signs and symptoms may include birth defects such as congenital heart disease, defects in the palate, most commonly related to neuromuscular problems with closure (velo-pharyngeal insufficiency), learning disabilities, mild differences in facial features, and recurrent infections. Infections are common in children due to problems with the immune systems T-cell mediated response that in some patients is due to an absent or hypoplastic thymus. 22q11.2 deletion syndrome may be first spotted when an affected newborn has heart defects or convulsions from hypocalcemia due to malfunctioning parathyroid glands and low levels of parathyroid hormone (parathormone). Affected individuals may also have any other kind of birth defect including kidney abnormalities and significant feeding difficulties as babies. Autoimmune disorders such as hypothyroidism and hypoparathyroidism ...

NIH Rare Diseases : 50 distal chromosome 18q deletionsyndromeis a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material at the end of the long arm (q) of chromosome 18. the severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. features that often occur in people with distal chromosome 18q deletion syndrome include developmental delay, intellectual disability, behavioral problems and distinctive facial features. chromosome testing of both parents can provide more information on whether or not the deletion was inherited. in most cases, parents do not have any chromosomal anomaly. however, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. the balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an ...
Background. 22q11.2 deletion syndrome (22q11.2DS) is associated with a high risk of childhood as well as adult psychiatric disorders, in particular schizophrenia. Childhood cognitive deterioration in 22q11.2DS has previously been reported, but only in studies lacking a control sample.. Aims. To compare cognitive trajectories in children with 22q11.2DS and unaffected control siblings.. Method. A longitudinal study of neurocognitive functioning (IQ, executive function, processing speed and attention) was conducted in children with 22q11.2DS (n = 75, mean age time 1 (T1) 9.9, time 2 (T2) 12.5) and control siblings (n = 33, mean age T1 10.6, T2 13.4).. Results. Children with 22q11.2DS exhibited deficits in all cognitive domains. However, mean scores did not indicate deterioration. When individual trajectories were examined, some participants showed significant decline over time, but the prevalence was similar for 22q11.2DS and control siblings. Findings are more likely to reflect normal ...
22q13 deletion syndrome, also known as Phelan-McDermid syndrome, is a neurodevelopmental disorder characterized by intellectual disability, hypotonia, delayed or absent speech, and autistic features. SHANK3 has been identified as the critical gene in the neurological and behavioral aspects of this syndrome. The phenotype of SHANK3 deficiency has been described primarily from case studies, with limited evaluation of behavioral and cognitive deficits. The present study used a prospective design and inter-disciplinary clinical evaluations to assess patients with SHANK3 deficiency, with the goal of providing a comprehensive picture of the medical and behavioral profile of the syndrome. A serially ascertained sample of patients with SHANK3 deficiency (n = 32) was evaluated by a team of child psychiatrists, neurologists, clinical geneticists, molecular geneticists and psychologists. Patients were evaluated for autism spectrum disorder using the Autism Diagnostic Interview-Revised and the Autism Diagnostic

In all cases the microdeletion was correctly detected without any false-positive or false-negative results. Starting May 2016, the results of the validation study were confirmed during pilot projects in several European countries with the aim ...
The features of this syndrome vary widely, even among affected members of the same family, and involve many parts of the body. Characteristic signs and symptoms include heart defects that are often present from birth, an opening in the roof of the mouth (a cleft palate) or other palate defects, and mild differences in facial features. People with 22q11.2 deletion syndrome often experience recurrent infections caused by problems with the immune system, and some develop autoimmune disorders such as rheumatoid arthritis and Graves disease. Affected individuals may also have kidney abnormalities, low levels of calcium in the blood (which can result in seizures), a decrease in blood platelets (thrombocytopenia), significant feeding difficulties, and hearing loss. Skeletal differences are possible, including mild short stature and, less frequently, abnormalities of the spinal bones.. Many children with 22q11.2 deletion syndrome have developmental delays and learning disabilities. Later in life, they ...
Substantial evidence exists supporting a major contributory role for genes in the causation of schizophrenia,1-3 a psychiatric illness characterised by hallucinations, delusions, disorganised thinking, alogia, avolition and other negative symptoms.4. A micro-deletion at chromosome 22q11, the most frequent interstitial deletion found in humans, has been implicated in the onset of schizophrenia. This aberration occurs in approximately 1 in every 4 000 live births (a familial type occurs in ,5% of reported cases) and its occurrence is associated with a variable phenotype. The prevalence of psychosis in those with 22q11 deletion syndrome is high (~25%), suggesting that haploinsufficiency of a gene or genes in this region may confer a substantially increased risk.5 It is therefore not surprising that approximately 1 in 4 children with 22q11 deletion syndrome could develop schizophrenia over their lifetime.6. The 22q11 micro-deletions have been characterised and mainly involve two areas of 3 Mb (87% ...
We identified two patients with a heterozygous deletion encompassing CTCF. Gregor et al 1 reported that intellectual disability, microcephaly and growth retardation are shared clinical features in patients with a CTCF mutation. In our study, both patients showed comparable features to those in the previous report. Our patients also showed hypertelorism, epicanthus, thin upper lip and abnormalities of fingers, which also appeared in the reported patients, indicating that haploinsufficiency of CTCF may produce a recognisable clinical syndrome.1 It is of note that our patients showed similar phenotypes to those in previously reported patients even though they carried different-sized deletions. Therefore, at least in our patients, CTCF appeared to be a major determinant of the phenotype, and other deleted genes may not have significant dosage-sensitive effects. The previous study theorised the clinical features in the reported patients were due to haploinsufficiency due to mutation, yet it was not ...
This study provides novel insight into the genotype-phenotype correlations of the rare chromosomal disorder del2q37 syndrome. First, this case manifests typical clinical features of del2q37 syndrome, while the phenotypic presentation because of the 1p36 duplication was less evident except for intelligence disability [18]. This finding suggests that haploinsufficiency of the genes at 2q37, rather than the segmental duplications of 1p36 or 20p12, shows dominant effects on the phenotypic presentation. Specific gene functions of GPCPD1 and the duplication of 20p12 remain to be clarified, structural variations at 20p14.3, wherein this gene is located, were identified in healthy individuals of Korean ethnicity [19]. Therefore, the 20p14.3 duplication spanning the GPCPD1 locus was unlikely to alter the phenotype of del2q37 syndrome and to produce the carcinogenic condition. While the present case did not show profound phenotype of intellectual disability compared to other cases in the literature, we ...

... is a chromosomal disorder in which there are three copies of chromosome 22 rather than two. It is a frequent cause of spontaneous abortion during the first trimester of pregnancy . Progression to the second trimester and live birth are rare. This disorder is found in individuals with an extra copy or a variation of chromosome 22 in some or all cells of their body. There are many kinds of disorders associated with Trisomy 22: Emanuel Syndrome is named after the genetic contributions made by researcher Dr. Beverly Emanuel. This condition is assigned to individuals born with an unbalanced 11/22 translocation . That is, a fragment of chromosome 11 is moved, or translocated, to chromosome 22. 22q11 Deletion Syndrome is a rare condition which occurs in approximately 1 in 4000 births. This condition is identified when a band in the q11.2 section of the arm of chromosome 22 is missing or deleted. This condition has several different names: 22q11.2 Deletion Syndrome, Velocardiofacial syndrome,

This study demonstrates, for the first time, that the in-hospital and long-term clinical outcomes in patients undergoing a coronary intervention are equivalent using the novel technique of DS compared with the more conventional technique of balloon angioplasty followed by stenting. This similar outcome was achieved despite more high risk characteristics in DS group, including a higher frequency of previous CABGs, vein graft interventions and thrombus at the treatment site. These outcomes were achieved with shorter procedure times and decreased utilization of contrast agent and equipment in the DS group.. Direct stenting has become increasingly popular with the availability of more deliverable stents. This study, however, includes our early experience using the first-generation Palmaz-Schatz and Gianturco-Roubin stents, although the majority of DS procedures employed second-generation stents such as the ACS Multilink stent. This technique has been advocated previously in a select group of ...
Chromosome 22q11.2 heterozygous deletions cause the most common deletion syndrome, including the DiGeorge syndrome phenotype. Using a mouse model of this deletion (named Df1) we show that the aortic arch patterning defects that occur in heterozygously deleted mice (Df1/+) are associated with a differentiation impairment of vascular smooth muscle in the 4th pharyngeal arch arteries (PAAs) during early embryogenesis. Using molecular markers for neural crest, endothelial cells and vascular smooth muscle, we show that cardiac neural crest migration into the 4th arch and initial formation of the 4th PAAs are apparently normal in Df1/+ embryos, but affected vessels are growth-impaired and do not acquire vascular smooth muscle. As in humans, not all deleted mice present with cardiovascular defects at birth. However, we found, unexpectedly, that all Df1/+ embryos have abnormally small 4th PAAs during early embryogenesis. Many embryos later overcome this early defect, coincident with the appearance of ...

Doctors do not know what causes early hypocalcemia.. Late hypocalcemia is rare and has a number of known causes. Late hypocalcemia is usually caused by drinking cows milk or formula that has too much phosphate. It may be connected to calcium and phosphorus levels in the body. It can also be caused by a problem with parathyroid hormone. This hormone is made by the parathyroid glands in the neck. It helps keep the amount of calcium and phosphorus at a normal level in the blood. Low parathyroid hormone levels can cause too little calcium in the blood. A number of conditions, such as DiGeorge syndrome (22q11.2 deletion syndrome), may cause low parathyroid hormone levels. ...
Patients with hypoparathyroidism develop radiologic opacities in the basal ganglia and other parts of the brain (1, 2). The condition is believed to be relatively rare in surgical hypoparathyroidism (3-5), presumably because patients with this disorder are treated more expeditiously than are patients with other forms of hypoparathyroidism. We have recently used computerized tomography to demonstrate intracerebral calcification in four patients with surgical hypoparathyroidism whose skull roentgenograms showed no abnormality.. Patient 1 is a housewife who developed tetany after thyroidectomy at age 34 years and was given calcium intravenously in the immediate postoperative period. No further bouts of tetany occurred, ...

Most cleft lips and palates are a one-off and its unlikely youll have another child with the condition.. The risk of having a child with a cleft lip or palate is slightly increased if youve had a child with the condition before, but the chances of this happening are thought to be around 2-8%.. If either you or your partner were born with a cleft, your chance of having a baby with a cleft is also around 2-8%. Most children of parents who had a cleft will not be born with a cleft.. The chances of another child being born with a cleft or of a parent passing the condition to their child can be higher in cases related to genetic conditions.. For example, a parent with 22q11 deletion syndrome (DiGeorge syndrome) has a 50% chance of passing the condition to their child.. ...

The researchers selected 29 children-16 boys and 13 girls-for additional scrutiny, administering two tests. The Autism Diagnostic Observation Schedule (ADOS), a gold-standard assessment for autism, was administered to the children. The Social Communication Questionnaire (SCQ), a 40-question parent screening tool for communication and social functioning based on the Autism Diagnostic Interview-Revised, was administered to their parents.. Typically, a diagnosis of autism spectrum disorder requires elevated scores on both a parent report measure, such as the SCQ, and a directly administered assessment such as the ADOS. Prior studies of autism in chromosome 22q11.2 deletion syndrome have only used parent report measures.. Only five of the 29 children had scores in the elevated range on the ADOS diagnostic tool. Four of the five had significant anxiety. Only two-7 percent-had SCQ scores above the cut off. No child had both SCQ and ADOS scores in the relevant ranges that would lead to an ASD ...

SHANK3 is a synaptic scaffolding protein and plays an important role in neuronal development. SHANK3 interacts with various synaptic molecules, including post-synaptic density-95 (PSD-95), homer and GluR1 AMPA receptor. SHANK3 gene is a causable gene of the Phelan- McDermid syndrome (also known as the 22q13.3 deletion syndrome), whose manifestation is global developmental delay and autistic behavior, especially shows severe speech and language deficit. Additionally since cumulative gene analysis in autistic subjects identified several mutations in SHANK3 gene, including deletion and duplication in a particular region, abnormality of SHANK3 gene is thought the be related with the neuropathology of autism spectrum disorder (ASD ...

Chromosome 22q11 fluorescence in situ hybridisation (FISH) studies were performed on 33 consecutive individuals attending a paediatric cardiology clinic with tetralogy of Fallot. Seven children had 22q11 microdeletions but only four had other clinical features associated with the newly recognised chromosome 22 deletion syndrome (CATCH 22). Chromosome 22q11 FISH studies should therefore be performed on all patients with tetralogy of Fallot.. ...
One copy of the q13 portion of chromosome 22 is either missing or otherwise mutated in SHANK3 deficiency, also known as Phelan-McDermid Syndrome or 22q13 Deletion Syndrome (22q13DS). The area in question contains the gene SHANK3, and there is overwhelming evidence that it is the loss of one copy of SHANK3 that produces the neurological and behavioral aspects of the syndrome. The SHANK3 gene is key to the development of the human nervous system, and loss of SHANK3 can impair the ability of neurons to communicate with one another ...
What started as a dream of six families united by the challenges of autism and driven by a desire to help families and the community, is now an internationally renowned center for neurodevelopmental disorders. The MIND Institute is dedicated to finding treatments, causes and preventions, and providing education for neurodevelopmental disorders.

RNA-binding protein 8A is a protein that in humans is encoded by the RBM8A gene. This gene encodes a protein with a conserved RNA-binding motif. The protein is found predominantly in the nucleus, although it is also present in the cytoplasm. It is preferentially associated with mRNAs produced by splicing, including both nuclear mRNAs and newly exported cytoplasmic mRNAs. It is thought that the protein remains associated with spliced mRNAs as a tag to indicate where introns had been present, thus coupling pre- and post-mRNA splicing events. Previously, it was thought that two genes encode this protein, RBM8A and RBM8B; it is now thought that the RBM8B locus is a pseudogene. Two alternative start codons result in two forms of the protein, and this gene also uses multiple polyadenylation sites. RBM8A has been shown to interact with IPO13, MAGOH and UPF3A.

In recent years numerous studies have indicated the importance of microRNAs (miRNA/miRs) in human pathology. Down syndrome (DS) is the most prevalent survivable chromosomal disorder and is attributed to trisomy 21 and the subsequent alteration of the dosage of genes located on this chromosome. A number of miRNAs are overexpressed in down syndrome, including miR‑155, miR‑802, miR‑ 125b‑2, let‑7c and miR‑99a. This overexpression may contribute to the neuropathology, congenital heart defects, leukemia and low rate of solid tumor development observed in patients with DS. MiRNAs located on other chromosomes and with associated target genes on or off chromosome 21 may also be involved in the DS phenotype. In the present review, an overview of miRNAs and the haploinsufficiency and protein translation of specific miRNA targets in DS are discussed.

Two hypotheses, termed quorum sensing (QS) and diffusion sensing (DS), have been suggested as competing explanations for why bacterial cells use the local concentration of small molecules to regulate numerous extracellular behaviours. Here, we show that: (i) although there are important differences between QS and DS, they are not diametrically opposed; (ii) empirical attempts to distinguish between QS and DS are misguided and will lead to confusion; (iii) the fundamental distinction is not between QS and DS, but whether or not the trait being examined is social; (iv) empirical data are consistent with both social interactions and a role of diffusion; (v) alternate hypotheses, such as efficiency sensing (ES), are not required to unite QS and DS. More generally, work in this area illustrates how the use of jargon can obscure the underlying concepts and key questions.
One of the difficulties here is that even those who see themselves as defending the rights of persons with Down Syndrome are perpetuating their own unsupported generalizations. I have a son with DS who does x… or I know of a woman with DS who does y… does not translate to any conclusion at all regarding the competence of people with Down Syndrome to do anything. There is a range of capabilities, across the board.. My son with Down Syndrome, in his twenties, is incapable of caring for a child. That most males with DS are sterile does not address the problem, as he would be entering a state which is itself ordered to the procreation and raising of children, something which he could not in principle do. I hear wonderful stories from parents with children with DS who praise God for the gift of a son or daughter capable of also being a mom or dad, as they should. But do not assume that because some are capable, all are. Fr. Toms question is not unfeeling, or an attempt to defend an ...
In the other narrative is the story of another kind of specialness. Your child is an angel. A miracle. Gods love embodied in human form. This story says that our kids love better than other kid. They are sent to us to teach us how to be better humans. The extra chromosome endows them with super powers usually of love. This is the story that tells us that kids with Ds are "sweet but stubborn." The children in this story are always photo shopped beautiful. Perfect and angelic as they gaze out at the viewer. Passive. These are the children people exclaim over but that they dont see as quite human. These children do not grow into adults but are frozen in the world of a glossy 8 X 10. When I found I was pregnant with a child that had Ds, I found these two stories. There were very few stories where parents were saying "Eh I got a kid." I remember after Jude was born I found the blog 21 + 21 + 21 = ? and fell in love with the header on her blog "Were not sad and life isnt hard. Theres a lot of ...
Clothes: I have discovered that my daughter is long in the trunk, but has short limbs. Some of this is genetic and some of it is the DS. Children with DS are often diagnosed as such in utero by having shorter femurs (leg) and shorter humerus (arm). I still have to roll the cuffs on the sleeves and pant legs, the bodies of the PJs and onsies are still baggy, but I cannot snap the bottoms of the onsies. She is too long. So, I guess we will be moving up to 6-9 month-size clothing ...

What is DiGeorge Syndrome ? DiGeorge syndrome is a genetic disorder that results from a defect in chromosome 22. Individuals with DiGeorge syndrome have a part
The severity level of DiGeorge syndrome including the associated health complications tend to differ from one patient to another. A majority of the affected individuals have to seek treatment from different types of specialists. Initially, DiGeorge syndrome was referred to by different names such as velocardiofacial syndrome, etc., before the cause was identified as an error occurring in chromosome 22. One may note that despite the fact that the term 22q11.2 deletion syndrome is often used in the current circumstance and which undoubtedly describes the condition, the older names of the condition are also recognized and used today.. ...

Q: What is DiGeorge syndrome?A: DiGeorge syndrome (DGS) is a genetic disorder caused by the deletion of some of the genes on chromosome 22. There is a lot of variability in how patients are affected by this syndrome, with the manifestations in an individual person depending on exactly which genes are deleted.DGS affects about one in every 5,000 babies. Although DGS may be inherited (in a dominant fashion, so if either parent has it there is a 50 percent chance the child will inherit it), over

Medical definition of DiGeorge syndrome: a rare congenital disease that is characterized especially by absent or underdeveloped thymus and parathyroid glands, heart defects, immunodeficiency, hypocalcemia, and characteristic facial features (as wide-set eyes, small jaws, and low-set ears) and is typically caused by a deletion on the chromosome numbered 22.
Defined genetically only (chromosome 22q11.2 deletion, TBX mutation, chromosome 10p13-14 deletion) [ ] Classic clinical triad for complete DiGeorge syndrome: (Conotruncal cardiac anomaly, hypocalcemia, CD3 T cells , 500 /mm3 in the first 3 months of life) [ ] Combination of genetic and phenotypic features (Mark all that apply) Conotruncal cardiac anomaly or cardiothoracic vascular anomaly Cleft palate (frank clefting or submucous cleft) Velopharyngeal insufficiency/ hypernasal speech ...
Researchers recently studied a highly sophisticated cellular machine that acts as a guard for the genome against harmful mutations and that evolution cannot explain.1. Humans have two sets of 23 chromosomes, and a mutational deletion in chromosome 22 causes a disease called DiGeorge syndrome in which heart and immune system defects occur, in addition to learning difficulties, mental retardation, and psychiatric disorders. The deletion eliminates a protein and stops the formation of a key piece of cellular machinery called a microprocessor.. The microprocessor is actually a working complex of two important proteins called Drosha and DGCR8 (DiGeorge syndrome critical region 8). The mutation causing the microprocessor to be defective affects DGCR8.2 The microprocessor protein complex itself gets its name from the fact that it processes an important group of molecules called microRNAs. MicroRNAs are small molecules that help regulate gene expression.3. It turns out that the microprocessor does ...

Haploinsufficiency of TBX1, encoding a T-box transcription factor, is largely responsible for the physical malformations in velo-cardio-facial /DiGeorge/22q11.2 deletion syndrome (22q11DS) patients. Cardiovascular malformations in these patients are highly variable, raising the question as to whether DNA variations in the TBX1 locus on the remaining allele of 22q11.2 could be responsible. To test this, a large sample size is needed. The TBX1 gene was sequenced in 360 consecutive 22q11DS patients. Rare and common variations were identified. We did not detect enrichment in rare SNP (single nucleotide polymorphism) number in those with or without a congenital heart defect. One exception was that there was increased number of very rare SNPs between those with normal heart anatomy compared to those with right-sided aortic arch or persistent truncus arteriosus, suggesting potentially protective roles in the SNPs for these phenotype-enrichment groups. Nine common SNPs (minor allele frequency, MAF | 0.05) were

A number of histone methyltransferases have been identified and biochemically characterized, but the pathologic roles of their dysfunction in human diseases like cancer are not well understood. Here, we demonstrate that Wolf-Hirschhorn syndrome candidate 1 (WHSC1) plays important roles in human carcinogenesis. Transcriptional levels of this gene are significantly elevated in various types of cancer including bladder and lung cancers. Immunohistochemical analysis using a number of clinical tissues confirmed significant up-regulation of WHSC1 expression in bladder and lung cancer cells at the protein level. Treatment of cancer cell lines with small interfering RNA targeting WHSC1 significantly knocked down its expression and resulted in the suppression of proliferation. Cell cycle analysis by flow cytometry indicated that knockdown of WHSC1 decreased the cell population of cancer cells at the S phase while increasing that at the G(2)/M phase. WHSC1 interacts with some proteins related to the WNT pathway
I was really scared about what the scars from open-heart surgery look would look like. Today I did a google search. Theyre not nearly as bad as I imagined. The survival rate for this surgery is around 80% and wed have to travel to get it done as its not performed in Madison. Unfortunately, his first open-heart surgery will not be his last. Our pediatric cardiologist said hell need another one around 1 year, a third around 6 or 7, and then every ten years after that. The heart defect is only the beginning. Apparently, in some babies born with truncus, the defect is only one symptom of a larger problem. There are several syndromes that could have caused this defect including some that are fatal (trisomy 18, trisomy 13) and some that include retardation and failure of other organs (diGeorge syndrome, Downs Syndrome, VCFS, 22q11.2). So far there are no indications that Turnip has any of these problems, but I dont think well know for sure until he is born as Im leaning away from having an ...
An increasing number of familial cases suggest that MRKH syndrome can be inherited as an autosomal dominant incompletely penetrant trait, either due to single gene mutation or chromosomal imbalances [1]. Clinical features are consistent with a developmental defect attributable to an initial affection of the intermediate mesoderm leading to an alteration of the blastema of the cervicothoracic somites and the pronephric ducts [6], but developmental genes investigated, such as WT1, HOXA7, HOXA13 and PBX1, did not reveal any pathogenic mutation [7, 8]. Among chromosome causes, an identical t(12;14)(q14;q31) detected in two unrelated Indian females, a maternally inherited terminal deletion of 4q and 22q11.21 deletion, overlapping the DiGeorge syndrome region, have been described in females with syndromic MRKH. However, so far no candidate gene was identified in the unbalanced regions [9-11].. Array-CGH technique has offered in the last years new opportunities to discover cryptic chromosome imbalances ...
22q11.2 deletion, the most common microdeletion syndrome within the general population, is estimated to have a prevalence of 1 in 3000 to 6000. Non-invasive prenatal testing has recently expanded to include screening for several microdeletions including 22q11.2. Given the expansion of prenatal screening options to include microdeletions, it is important to understand the limits of this technology and the variety of reasons that a discordant positive result can occur. Here, we describe a case of a pregnant woman who received a positive non-invasive prenatal maternal plasma screen for 22q11.2 deletion. Maternal and postnatal neonatal peripheral blood cytogenetic, PCR, and fluorescence in situ hybridization studies were normal, but the placenta was mosaic for 22q11.2 deletion in two of three biopsy sites. This case illustrates both the complexities of pre- and post-test counseling for microdeletion screening and the potential for a discordant positive microdeletion result because of confined placental

People who have normal immune systems typically have the symptoms already mentioned. Those undergoing chemotherapy for leukemia or lymphoma, those with HIV or AIDS, and those born with poor immune systems (SCID, DiGeorge Syndrome, etc.) will often have much more severe presentations. Examples include ulcers in a wider distribution than normal, larger-than-normal ulcers, and ulcers that heal poorly or not at all.. A rare complication (only 1 in 500,000 people) is a brain infection called herpes simplex encephalitis. However, this is usually associated with HSV-1, which usually causes oral herpes or in neonatal herpes virus infections.. Perhaps one of the most feared consequences of genital herpes infections is infection of a newborn, or neonatal infection. Unlike genital herpes infections in adults, neonatal herpes can have very grave outcomes, including death. The incidence is between 1 in 2,000 and 1 in 10,000 live births, and the incidence is higher in premature births than in full-term ...
However, the scarcity of donor organs means many people will not survive the wait for transplantation," said Dr. Lagasse, whose lab is at the McGowan Institute. "Cell therapies are being explored, but introducing cells into tissue already ravaged by disease decreases the likelihood of successful engraftment and restoration of function.". In the study, his team tested the possibility of using lymph nodes, which are abundant throughout the body and have a rich blood supply, as a new home for cells from other organs in what is called an "ectopic" transplant.. They injected healthy liver cells from a genetically-identical donor animal into lymph nodes of mice at various locations. The result was an enlarged, liver-like node that functioned akin to the liver; in fact, a single hepatized lymph node rescued mice that were in danger of dying from a lethal metabolic liver disease. Likewise, thymus tissue transplanted into the lymph node of mice that lacked the organ generated functional immune systems, ...
The TBX1 gene is a member of the T-box gene family of transcription factors that is characterised by a conserved DNA binding domain throughout the metazoan evolution [19]. The members of the T-box gene family play a crucial role in a wide variety of developmental processes in vertebrate and invertebrate embryos [20]. The biological importance of these genes is emphasised by the phenotypes of the patient carried loss-of-function mutations of TBX3 and TBX5[21-23].. TBX1 haploinsufficiency has long been known to be crucial in the aetiology of 22q11DS. Mutation analysis has revealed frameshift and missense mutations of TBX1 in patients with the 22q11DS-phenotype, but no detectable deletion [4, 24, 25]. Animal model experimental evidence suggests that Tbx1 is required for normal heart development [26, 27]; however, no unequivocal mutation of TBX1 has been discovered in isolated CTDs patients. Tbx1 is expressed in the secondary heart field (SHF) and positively regulates SHF cell proliferation and ...
... is a congenital heart condition in which the embryological structure known as the truncus arteriosus never fully divides into two independent blood vessels: the pulmonary artery and aorta. In the heart of a healthy person, the aorta, containing oxygen-rich, blood comes out of the left ventricle, and the pulmonary artery, containing deoxygenated blood, comes out of the right ventricle; thus, these two blood vessels are separate from each other. In truncus arteriosus disease, a single artery comes out of the two ventricles. There is usually also a large hole between the two ventricles (ventricular septal defect). As a result, the blue (without oxygen) and red (oxygen-rich) blood mix ...
Background: The chromosome 17q21.31 microdeletion syndrome is a novel genomic disorder that has originally been identified using high resolution genome analyses in patients with unexplained mental retardation. Aim: We report the molecular and/or clinical characterisation of 22 individuals with the 17q21.31 microdeletion syndrome. Results: We estimate the prevalence of the syndrome to be 1 in 16 000 and show that it is highly underdiagnosed. Extensive clinical examination reveals that developmental delay, hypotonia, facial dysmorphisms including a long face, a tubular or pear-shaped nose and a bulbous nasal tip, and a friendly/amiable behaviour are the most characteristic features. Other clinically important features include epilepsy, heart defects and kidney/urologic anomalies. Using high resolution oligonucleotide arrays we narrow the 17q21.31 critical region to a 424 kb genomic segment (007: 41046729-41470954, hg17) encompassing at least six genes, among which is the gene encoding microtubule
Lymph nodes can provide a suitable home for a variety of cells and tissues from other organs, suggesting that a cell-based alternative to whole organ transplantation might one day be feasible.
The 2p15p16.1 microdeletion syndrome has a core phenotype consisting of intellectual disability, microcephaly, hypotonia, delayed growth, common craniofacial features, and digital anomalies. So far, more than 20 cases of 2p15p16.1 microdeletion syndrome have been reported in the literature; however, the size of the deletions and their breakpoints vary, making it difficult to identify the candidate genes. Recent reports pointed to 4 genes (XPO1, USP34, BCL11A, and REL) that were included, alone or in combination, in the smallest deletions causing the syndrome. Here, we describe 8 new patients with the 2p15p16.1 deletion and review all published cases to date. We demonstrate functional deficits for the above 4 candidate genes using patients lymphoblast cell lines (LCLs) and knockdown of their orthologs in zebrafish. All genes were dosage sensitive on the basis of reduced protein expression in LCLs. In addition, deletion of XPO1, a nuclear exporter, cosegregated with nuclear accumulation of one of ...

Periodontal disease (PD) is characterized as an inflammatory process that compromises the support and protection of the periodontium. Patients with Downs syndrome (DS) are prone to develop PD. Neutrophils (NE) are the first line of defense against infection and their absence sets the stage for disease. Aim: To compare the activity and function of NE in the peripheral blood from DS patients with and without PD, assisted at the Center for Dental Assistance to Patients with Special Needs affiliated with the School of Dentistry of Araçatuba, Brazil. Methods: Purified NE were collected from peripheral blood of 22 DS patients. NE were used to detect the 5-lypoxigenase (5-LO) expression by RT-PCR. Plasma from peripheral blood was collected to measure tumor necrosis factor-a (TNF-α) and interleukin-8 (IL-8) by ELISA and nitrite (NO3) using a Griess assay. Results: Data analysis demonstrated that DS patients with PD present high levels of TNF-a and IL-8 when compared with DS patients without PD. ...
Tumor angiogenesis is a hallmark of cancer, and plays a critical role in tumor growth, expansion, and metastasis. Both physiological and pathological angiogenesis is assumed to be regulated by the balance between pro and anti-angiogenic factors. One of the best characterized and most potent pro-angiogenic regulators is vascular endothelial growth factor, or VEGF. Calcineurin signaling is an important mediator of VEGF signaling in endothelial cells. Negative regulation of calcineurin by increased expression of its endogenous inhibitor, Down Syndrome Candidate Region-1 (DSCR1), suppresses tumor growth and angiogenesis. However, a potent pharmacological calcineurin inhibitor, the commonly used immunosuppressant cyclosporin A (CsA), significantly increases the incidence of cancer in organ transplant recipients. The mechanism by which CsA promotes cancer in this patient population is not well understood and despite the significance of calcineurin signaling in endothelial cells, the consequences of CsA on
Most children with 22q11.2DS are missing about 50 genes. Researchers dont yet know the exact function of many of these genes. But missing the gene TBX1 on chromosome 22 likely causes the syndromes most common physical symptoms. These include heart problems and cleft palate. The loss of another gene (called COMT) may also explain the higher risk for behavior problems and mental illness. About 9 in 10 cases of 22q11.2DS happen by chance (randomly). They occur when the egg is fertilized. Or they occur early in a babys growth in the mothers uterus. This means that most children with the disorder have no family history of it. But a person with the condition can pass it on to his or her children. About 1 in 10 cases are inherited from the mother or the father. When the condition is inherited, other family members could also be affected. A person who has this chromosome deletion has a 1 in 2 chance of passing the problem to a child. So both parents can have their blood studied to look for the ...
MONDAY, Sept. 9 (HealthDay News) -- A genetic deletion may be linked to some cases of early onset Parkinsons disease, researchers say.. The investigators found that people aged 35 to 64 who were missing DNA on a specific part of chromosome 22 were about 90 times more likely to develop Parkinsons than people from the same age group in the general population.. People with this inherited genetic condition -- called 22q11.2 deletion syndrome -- have about 50 genes missing on chromosome 22. The condition occurs in about one in 2,000 to 4,000 people, and those with this genetic deletion may have birth defects (including heart defects), learning or speech difficulties, anxiety disorders, or schizophrenia.. Previously reported cases of patients with 22q11.2 deletion syndrome and Parkinsons disease symptoms have indicated that there may be a link between the two conditions, according to the researchers from the Center for Addiction and Mental Health and University Health Network in Toronto..

Learn what patients need to know about truncus arteriosus, a rare congenital heart defect in which one common valve comes out of the heart, instead of two.
Truncus arteriosus is a heart defect that is present at birth (congenital). It occurs when there is an abnormal connection between the aorta and pulmonary artery. Normally, the aorta and the pulmonary artery are separate.
BACKGROUND: Repair of truncus arteriosus communis (TAC) in the neonatal and early infant period has become standard practice in many centers. We report our experience on early primary repair of TAC, with a focus on early and midterm results. METHODS:
A class of three substances has been isolated in highly purified form and in substantially pure form by utilizing thymus tissue as a source material. These three substances are designated thymone A, thymone B and thymone C. Thymones A and B are new peptides which yield approximately 13 and 14 individual amino acid moieties, respectively, on acid hydrolysis. Thymones A and B are chemically characterized by electrophoretic and chromatographic values which are appropriate for substances which are substantially pure. Thymone C was highly purified and its biological activity was reproducibly detected and measured. Thymones A, B and C stimulate the proliferation of lymphocytes. Thymone A stimulates the formation of cyclic adenosine monophosphate. Thymone B stimulates the formation of cyclic guanosine monophosphate. The biological activities of these thymones to stimulate the proliferation of lymphocytes and the formations of cyclic nucleotides are basic hormonal functions for the therapeutic enhancement of
We show rat thymus to express several cytochrome P450 and other steroid-metabolizing enzymes and demonstrate tissue-specific metabolism of testosterone. We also demonstrate an age-dependent transcript expression of isoforms of P450 and 17β-HSDH, as well as the androgen receptor, in thymus tissue of fetal and adult rats. We thus extend earlier findings of a time-dependent P450 monooxygenase gene expression during liver organogenesis to the thymus (Borlakoglu et al., 1993; Yang et al., 1995; Juchau et al., 1998).. Importantly, steroid hormones are versatile signaling molecules and are metabolized via several enzyme systems, including P450 monooxygenases, hydroxysteroid dehydrogenases/reductases, and aromatases, and are usually bound reversibly to carrier proteins in the blood. Upon receptor-mediated endocytosis (Porto et al., 1995), they interact specifically with steroid-hormone-receptor proteins in the cytoplasm and nucleus (Becker et al., 1986). Binding of the hormone activates the receptor, ...

The purpose of this case study was to determine which mathematical instructional strategies met the learning challenges of a primary-age child identified with 22q11DS. This study investigated the processes by which a young child with 22q11DS acquires mathematical concepts within classroom and tutoring settings. It placed emphasis on building knowledge of specific mathematical concepts and skills which are significant in a childs development of number sense and flexible use of mathematics in daily situations. This study is significant because it can be used to identify learning challenges of the 22q11DS population, develop understandings of how to best meet these students mathematical learning needs, and expand the awareness of general education and support service teachers. The current deficit of information concerning development of foundational mathematic concepts in students with 22q11DS makes meeting the educational needs of these students challenging. A qualitative case
