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.

AU - Antshel, Kevin M.. PY - 2018/10/1. Y1 - 2018/10/1. N2 - Objective: While individuals with 22q11.2 deletion syndrome (22q11DS) are at increased risk for a variety of functional impairments and psychiatric disorders, including psychosis, not all individuals with 22q11DS experience negative outcomes. Efforts to further understand which childhood variables best predict adult functional outcomes are needed, especially those that investigate childhood executive functioning abilities. Methods: This longitudinal study followed 63 individuals with 22q11DS and 43 control participants over 9 years. Childhood executive functioning ability was assessed using both rater-based and performance-based measures and tested as predictors of young adult outcomes. Results: Childhood global executive functioning ...
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 ...

AU - Nguyen, Vy. AU - McDonald-McGinn, Donna. AU - Zackai, Elaine. AU - Simon, Tony J. PY - 2006/5/22. Y1 - 2006/5/22. N2 - Children with chromosome 22q11.2 deletion syndrome commonly are found to have morphological brain changes, cognitive impairments, and elevated rates of psychopathology. One of the most commonly and consistently reported brain changes is reduced cerebellar volume. Here, we demonstrate that, in addition to the global cerebellum reductions previously reported, volumetric reductions of the anterior lobule and the vermal region of the neo-cerebellum in the mid-sagittal plane best differentiate children with the deletion from typically developing children. These results suggest that the morphological changes of specific portions of the cerebellum may be an important underlying substrate of ...
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 ...
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 ...
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 ...
UC Davis researchers have found that for children with the genetic disorder known as chromosome 22q11.2 deletion syndrome anxiety ― but not intelligence ― is linked to poorer adaptive behaviors that affect daily life. The developmental syndrome, which is associated with a constellation of physical, cognitive and psychiatric problems, usually is apparent at birth or early childhood, and leads to lifelong challenges.

We report the neuropsychological profile of a 4-year-old boy with the rare 18p deletion syndrome. We used a battery of standardized tests to assess his development in intellect, language, visuomotor integration, academic readiness, socialization, and emotional and behavioral health. The results showed borderline intellectual function except for low average nonverbal reasoning skills. He had stronger receptive than expressive language skills, although both were well below his age group. He had impaired visuomotor integration and pre-academic skills such as letter identification. Emotional and behavioral findings indicated mild aggressiveness, anxiety, low frustration tolerance, and executive function weaknesses, especially at home. Interestingly, he showed social strengths, responding to joint attention and sharing enjoyment with his examiner. With its assessment of development in many domains, this case report is among the first to characterize the neuropsychological and psychiatric function of ...
Thats why we studied the development of this structure in detail, continues the UNIGE researcher, so we could understand why some people affected by deletion syndrome eventually develop psychotic symptoms, while others dont.. 18-year study investigating the development of the hippocampus. The Geneva team has been following 275 patients aged 6 to 35 years for 18 years: a control groups of 135 individuals - i.e. individuals without genetic problems - and 140 people with deletion syndrome, including 53 with moderate to severe psychotic symptoms. They underwent an MRI every three years so that we could observe their brain development, says Valentina Mancini, a researcher in UNIGEs Department of Psychiatry.. This has helped us create a statistical model that measures and compares the development of the hippocampus in both groups of patients. It was discovered that the hippocampus of the group affected by deletion syndrome, although smaller from the beginning, followed a growth curve ...
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 ...

I hope your tests come back with good results marg,,,that would be great! take care of yourself and keep up the postive thoughts,even if you dont go off the lexapro,,,,,I try to explain to my husband that anti Ds are NOT miracle pills,that when you take them,you have to work at making yourself happy too,,,,,,so ya have the right attitude:) good luck and hope we talk ...

NIH Rare Diseases : 52 Proximal chromosome 18q deletion syndrome is a chromosome abnormality that occurs when there is a missing (deleted ) copy of genetic material from the part of the long (q) arm near the center 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 proximal chromosome 18q deletion syndrome include developmental delay , intellectual disability , and distinctive facial features. The might also have seizures , low muscle tone (hypotonia ), speech and language delays, obesity, and short stature . 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 ...
22q11.2 deletion syndrome (which is also known by several other names, listed below) is a disorder caused by the deletion of a small piece of chromosome 22. The deletion occurs near the middle of the chromosome at a location designated q11.2.22q11.2 deletion syndrome has many possible signs and symptoms that can affect almost any part of the body. Explore symptoms, inheritance, genetics of this condition.
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.
22q11.2 Deletion Syndrome (22q11.2DS) is one of the strongest known risk factors for schizophrenia. The syndrome provides a rare opportunity to prospectively examine development that precedes schizophrenia. 22q11.2DS is also associated with a range of psychiatric disorders and cognitive deficits. The overall aim of this thesis is to examine the neuropsychiatric phenotype of 22q11.2DS through a developmental lens. This thesis uses data from Cardiff Universitys ECHO (Experiences of CHildren with cOpy number variants) study which includes a longitudinal cohort of children with 22q11.2DS. Development in 22q11.2DS is contrasted to that of the unaffected siblings of children with 22q11.2DS. First psychopathology is examined longitudinally across early adolescence in 22q11.2DS. Children with 22q11.2DS have a significant burden of psychopathology across early adolescence, including attention-deficit/hyperactivity disorder (ADHD), anxiety disorders and autism spectrum disorder (ASD). There is a striking ...
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 ...
Objective The 22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion syndrome in humans. It is characterised by wide phenotypic variability, including congenital heart disease (CHD), immunodeficiency and scoliosis. However, little is known regarding the prevalence and characteristics of scoliosis in patients with 22q11.2DS. The objective of this study is to assess the prevalence of scoliosis, its characteristics and the association with CHD in patients with 22q11.2DS. ...

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% ...

Most patients (90%) with the Smith-Magenis syndrome have interstitial deletions in the short arm of chromosome 17 (17p11.2). However, it is included here since a few have heterozygous molecular mutations in the RAI1 gene which is located in this region. While there is considerable phenotypic overlap, individuals with chromosomal deletions have the more severe phenotype as might be expected. For example, those with RAI1 mutations tend to be obese and are less likely to exhibit short stature, cardiac anomalies, hypotonia, hearing loss and motor delays than seen in patients with a deletion in chromosome 17. However, the phenotype is highly variable among patients with deletions depending upon the nature and size of the deletion..

If parental chromosomes are normal, the risk for recurrence in sibs is less than ...
This is the first longitudinal study of cognition in 22q11.2DS that has compared different models of cognitive development. We are also the first study of cognitive deterioration in 22q11.2DS that has used a control group. This was possible because of the availability of a control sibling sample and the administration of identical cognitive measures at both time points. This methodology allowed us to explore whether cognitive decline represents a developmental lag or an absolute developmental deterioration. We found that cognitive deterioration is not a developmental feature specific to 22q11.2DS. Across all cognitive domains, we found no evidence that the group trajectory associated with 22q11.2DS represented developmental deterioration. This indicates that on average children with 22q11.2DS do continue to acquire ability and knowledge throughout childhood and adolescence. This is also consistent with findings in the Dunedin cohort, where children who later developed schizophrenia did not ...
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.. Dr. Anne ...

It has been estimated that about 10% of patients with autism also carry an identifiable genetic abnormality. One genetic syndrome that confers an increased ASD risk is 22q11.2 deletion syndrome (22q11.2 DS; velocardiofacal syndrome, VCFS), with up to about 40% of the patients developing ASD.
I just happened upon your blog. My nephew was diagnosed with 1p36 deletion syndrome when he was a year old. He is now 6. He loves music, books, people, and riding the bus to school. The Lord certainly knows which families to place these special kids in. While it is not easy, I know my brother and his wife would say that Carl has taught them more about life than any other person. I can relate to your story here about the brother being the protector. My nephew has 3 siblings. An older brother and sister, and a younger sister. Each of them know the Carl is special, but that doesnt stop them from involving him in their everyday life. Or his cousin who is the same age as him who is always so excited to see him and drag him around and tell him everything that is going on in a 6 year olds life. So, I was just encouraged to see another family love their child. God doesnt make mistakes. ...

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.
