Microdeletion 22q11 and oesophageal atresia. (1/42)

Oesophageal atresia (OA) is a congenital defect associated with additional malformations in 30-70% of the cases. In particular, OA is a component of the VACTERL association. Since some major features of the VACTERL association, including conotruncal heart defect, radial aplasia, and anal atresia, have been found in patients with microdeletion 22q11.2 (del(22q11.2)), we have screened for del(22q11.2) by fluorescent in situ hybridisation (FISH) in 15 syndromic patients with OA. Del(22q11.2) was detected in one of them, presenting with OA, tetralogy of Fallot, anal atresia, neonatal hypocalcaemia, and subtle facial anomalies resembling those of velocardiofacial syndrome. The occurrence of del(22q11.2) in our series of patients with OA is low (1/15), but this chromosomal anomaly should be included among causative factors of malformation complexes with OA. In addition, clinical variability of del(22q11.2) syndrome is further corroborated with inclusion of OA in the list of the findings associated with the deletion.  (+info)

Diagnostic and therapeutic problems in a case of prenatally detected fetal hydrocolpos. (2/42)

We report on a female fetus with prenatally suspected hydrometrocolpos. Postnatal evaluation additionally revealed ambiguous genitalia, anorectal atresia, vertebral segmentation anomalies and congenital intestinal aganglionosis. Colostomy was performed, but postoperative recovery was complicated by pulmonary hypertension and renal failure, resulting in death at day 18. Postmortem examination furthermore revealed a small ventricular septal defect, as well as rectovaginal and urethrovaginal fistulae, causing massive dilatation of the septated vagina (hydrocolpos). The possibility of an overlapping VACTERL and MURCS association is discussed.  (+info)

Double partial monosomies (10p- and Xp-) in a female baby with choanal atresia. (3/42)

Chromosomal abnormalities involving double partial monosomies are very rare. A female infant with non-mosaic monosomy 10p13-->10pter along with monosomy Xp11.4-->Xpter which arose de novo is described. The clinical manifestations of this patient included microcephaly, mild synophrys, short and down-slanted palpebral fissures, ptosis of the left eye, long eyelashes, a depressed nasal bridge, dysplastic ears, micrognathia, a short neck. sensorineural hearing impairment, and severe growth retardation. Left choanal atresia and laryngomalacia were detected by flexible fibroscopy. No signs of hypoparathyroidism or defective cellular immunity could be found. Fluorescence in situ hybridization (FISH) with whole-chromosome painting probes for chromosomes 10 and X was performed, which excluded the possibility of cryptic translocations of the involved chromosome segments. No submicroscopic chromosome 22q11 deletion could be found by FISH. Thus this very rare coexistence of double independent partial monosomies was confirmed. There are no previous reports of such concurrent double partial monosomies.  (+info)

A newborn lethal defect due to inactivation of retinaldehyde dehydrogenase type 3 is prevented by maternal retinoic acid treatment. (4/42)

The retinoic acid (RA) signal, produced locally from vitamin A by retinaldehyde dehydrogenase (Raldh) and transduced by the nuclear receptors for retinoids (RA receptor and 9-cis-RA receptor), is indispensable for ontogenesis and homeostasis of numerous tissues. We demonstrate that Raldh3 knockout in mouse suppresses RA synthesis and causes malformations restricted to ocular and nasal regions, which are similar to those observed in vitamin A-deficient fetuses and/or in retinoid receptor mutants. Raldh3 knockout notably causes choanal atresia (CA), which is responsible for respiratory distress and death of Raldh3-null mutants at birth. CA is due to persistence of nasal fins, whose rupture normally allows the communication between nasal and oral cavities. This malformation, which is similar to isolated congenital CA in humans and may result from impaired RA-controlled down-regulation of Fgf8 expression in nasal fins, can be prevented by a simple maternal treatment with RA.  (+info)

A case of Antley-Bixler syndrome with severe skeletal Cl. III malocclusion. (5/42)

Antley-Bixler syndrome is a disorder characterized by craniosynostosis, midface hypoplasia, choana blockade, and radiohumeral synostosis. However, the features of occlusion remain unclear. In this paper, we report a case of Antley-Bixler syndrome, a 7-year-old boy, from the viewpoint of orthodontics. From lateral cephalometric head film analysis, remarkable retardation of the anterior subcranial base, infraorbitale, and maxilla were notable, as was vertical growth restriction of the maxilla. The choana blockade tendency was also recognized. Moreover, although reverse occlusion was present, a mandibular retrognathic tendency was also present, and a short ramus mandible, remarkable mandibular vertical growth pattern, and skeletal open bite were present. In the dentition, two of the lower incisors were missing, and the present lower incisors were large. Maxillary and mandibular first molars were delayed in eruption. For treatment, the solutions to such remarkable skeletal problems were limited by the insufficiency of recovery of cranial formation after the operation. We planned a non-surgical treatment to expand the maxilla. It will be necessary to continually consider the treatment of his malocclusion as he continues to grow.  (+info)

SNP genotyping to screen for a common deletion in CHARGE syndrome. (6/42)

BACKGROUND: CHARGE syndrome is a complex of birth defects including coloboma, choanal atresia, ear malformations and deafness, cardiac defects, and growth delay. We have previously hypothesized that CHARGE syndrome could be caused by unidentified genomic microdeletion, but no such deletion was detected using short tandem repeat (STR) markers spaced an average of 5 cM apart. Recently, microdeletion at 8q12 locus was reported in two patients with CHARGE, although point mutation in CHD7 on chromosome 8 was the underlying etiology in most of the affected patients. METHODS: We have extended our previous study by employing a much higher density of SNP markers (3258) with an average spacing of approximately 800 kb. These SNP markers are diallelic and, therefore, have much different properties for detection of deletions than STRs. RESULTS: A global error rate estimate was produced based on Mendelian inconsistency. One marker, rs431722 exceeded the expected frequency of inconsistencies, but no deletion could be demonstrated after retesting the 4 inconsistent pedigrees with local flanking markers or by FISH with the corresponding BAC clone. Expected deletion detection (EDD) was used to assess the coverage of specific intervals over the genome by deriving the probability of detecting a common loss of heterozygosity event over each genomic interval. This analysis estimated the fraction of unobserved deletions, taking into account the allele frequencies at the SNPs, the known marker spacing and sample size. CONCLUSIONS: The results of our genotyping indicate that more than 35% of the genome is included in regions with very low probability of a deletion of at least 2 Mb.  (+info)

CHARGE syndrome: the phenotypic spectrum of mutations in the CHD7 gene. (7/42)

BACKGROUND: CHARGE syndrome is a non-random clustering of congenital anomalies including coloboma, heart defects, choanal atresia, retarded growth and development, genital hypoplasia, ear anomalies, and deafness. A consistent feature in CHARGE syndrome is semicircular canal hypoplasia resulting in vestibular areflexia. Other commonly associated congenital anomalies are facial nerve palsy, cleft lip/palate, and tracheo-oesophageal fistula. Specific behavioural problems, including autistic-like behaviour, have been described. The CHD7 gene on chromosome 8q12.1 was recently discovered as a major gene involved in the aetiology of this syndrome. METHODS: The coding regions of CHD7 were screened for mutations in 107 index patients with clinical features suggestive of CHARGE syndrome. Clinical data of the mutation positive patients were sampled to study the phenotypic spectrum of mutations in the CHD7 gene. RESULTS: Mutations were identified in 69 patients. Here we describe the clinical features of 47 of these patients, including two sib pairs. Most mutations were unique and were scattered throughout the gene. All patients but one fulfilled the current diagnostic criteria for CHARGE syndrome. No genotype-phenotype correlations were apparent in this cohort, which is best demonstrated by the differences in clinical presentation in sib pairs with identical mutations. Somatic mosaicism was detected in the unaffected mother of a sib pair, supporting the existence of germline mosaicism. CONCLUSIONS: CHD7 mutations account for the majority of the cases with CHARGE syndrome, with a broad clinical variability and without an obvious genotype-phenotype correlation. In one case evidence for germline mosaicism was provided.  (+info)

Multiple mutations in mouse Chd7 provide models for CHARGE syndrome. (8/42)

Mouse ENU mutagenesis programmes have yielded a series of independent mutations on proximal chromosome 4 leading to dominant head-bobbing and circling behaviour due to truncations of the lateral semicircular canal of the inner ear. Here, we report the identification of mutations in the Chd7 gene in nine of these mutant alleles including six nonsense and three splice site mutations. The human CHD7 gene is known to be involved in CHARGE syndrome, which also shows inner ear malformations and a variety of other features with varying penetrance and appears to be due to frequent de novo mutation. We found widespread expression of Chd7 in early development of the mouse in organs affected in CHARGE syndrome including eye, olfactory epithelium, inner ear and vascular system. Closer inspection of heterozygous mutant mice revealed a range of defects with reduced penetrance, such as cleft palate, choanal atresia, septal defects of the heart, haemorrhages, prenatal death, vulva and clitoral defects and keratoconjunctivitis sicca. Many of these defects mimic the features of CHARGE syndrome. There were no obvious features of the gene that might make it more mutable than other genes. We conclude that the large number of mouse mutants and human de novo mutations may be due to the combination of the Chd7 gene being a large target and the fact that many heterozygous carriers of the mutations are viable individuals with a readily detectable phenotype.  (+info)

Choanal atresia describes the congenital narrowing of the back of the nasal cavity that causes difficulty breathing in neonate. Choanal atresia is often associated with CHARGE, Treacher Collins and Tessier Syndrome. It is a rare condition that occurs in 1:7000 live births, seen in females twice as often as males, and affects bilaterally in roughly 50% of cases. Bilateral choanal atresia is usually repaired in the newborn period. Unilateral CA repair is often deferred until age 2-3 years. Stent placement has become optional as stentless repair is gaining popularity because this technique decreases foreign body reaction in the nasopharynx which in term decreases granulation formation. Transnasal endoscopic choanal atresia repair is performed by opening the atresia bilaterally, drilling out pterygoid bone as needed, and removal of the posterior septum and vomer. Normal mucosa is preserved as much as possible by elevating a lateral based mucosal flap to prevent scarring and restenosis. Postoperatively,
Choanal atresia is a congenital disorder where the back of the nasal passage (choana) is blocked, usually by abnormal bony or soft tissue (membranous) due to failed recanalization of the nasal fossae during fetal development. It can be unilateral or bilateral. Sometimes, a unilateral choanal atresia is not detected until much later in life because the baby manages to get along with only one nostril available for breathing. Bilateral choanal atresia is a very serious life-threatening condition because the baby will then be unable to breathe directly after birth as babies are obligate nasal breathers (they mainly use their noses to breathe). In some cases, this may present as cyanosis while the baby is feeding, because the oral air passages are blocked by the tongue, further restricting the airway. The cyanosis may improve when the baby cries, as the oral airway is used at this time. These babies may require airway resuscitation soon after birth. Sometimes babies born with choanal atresia also ...
We present the fourth published case of a child affected with choanal atresia following maternal treatment with carbimazole. The mother was receiving her highest dose of carbimazole at the crucial period for development of the choanae, between days 35 and 38 ...
Choanal atresia is narrowing of the rear opening of the nasal cavity. It is often associated with CHARGE, Treacher Collins syndrome, and Tessier syndrome.
Choanal atresia is a narrowing or blockage of the nasal airway by tissue. It is a congenital condition, meaning it is present at birth.
Neonates have to breathe through their nose because the entire length of their tongue abuts against the hard and soft palates, and because the high position of their epiglottis (at the level of the third and fourth cervical vertebrae compared with the fifth and sixth vertebrae in adults) causes increased resistance of the oral airway.. The nasal passages can be divided into 3 anatomic regions: pyriform aperture, middle nasal cavity and posterior choana. Anterior nasal obstructions are usually due to isolated pyriform aperture stenoses or a lack of cleavage of the frontal hemispheres, which results in holoprosencephaly in addition to a central maxillary incisor. Posterior obstructions, such as bilateral choanal atresia, are usually part of the CHARGE association (a syndrome of associated birth defects, including coloboma of the eye, heart anomaly, choanal atresia, growth retardation, and genital and ear anomalies).. Midnasal obstructions are often due to nasal edema from inflammation and ...

Baby Matt was born last September 10, 2017 with a rare condition known as CHARGE Syndrome and still fighting the condition in Pedia Intensive Care Unit(PICU) at Philippine General Hospital. CHARGE syndrome affects hearing, sight, breathing, feeding, heart function, and general development needs. Matt requires specialized care for all of these areas and medication might take years. A few minutes after Matt was born, he was intubated. He was later diagnosed to have a blocked nasal track on both nose( Bilateral Choanal Atresia), humming heart(suspected severe open heart condition), hydrocephalus, di george syndrome, physical deformities( ears and toes), too small genital, very low hemoglobin level and severe Pneumonia. My husband and I felt so bad knowing about his situation. We keep on asking ourselves what went wrong, what have we done, eat, etc... that might have caused this conditions, what have we done or have failed to do.

Description: CHARGE syndrome was initially defined as a non-random association of anomalies (Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies/deafness). In 1998, an expert group defined the major (the classical 4Cs: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies) and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. In 2004 a Netherlands study (Vissers, LELM, et.al) found a gene (CHD7 on 8Q12) which was implicated in 2/3 of those tested. This gene is responsible for encoding a number of DNA protein which is esential when neural crest cells are being formed and migrating. A negative genetic test for changes in the CHD7 gene can still result in a diagnosis of CHARGE ...
CHARGE syndrome is a condition that can disturb numerous areas of human body. As an abbreviation CHARGE stands for: coloboma, heart defects, atresia choanae, and retardation of growth, genital, and ear abnormalities. The configuration of malformations differs among individuals with this disorder, and the various health issues can be life-threatening during infancy and childhood. Affected individuals typically have several main features or a combination of major and minor appearances. Here we are presenting a case report of a neonate with CHARGE syndrome who underwent successful repair of choanal atresia under general anaesthesia with invasive monitoring.
Air, blood, bodily fluids, and waste products travel throughout the body in a system of vessels, tubes, and chambers that are often separated by valves. When a child is born with atresia, it means that a valve is missing or a tube is closed off. This interrupts the normal flow of blood, fluid, waste, or air, which can lead to a number of complications.. Most kinds of atresia are serious and can be fatal if they go untreated. Treatment usually involves surgery while the child is still an infant.. The types of atresia are named for the body parts they affect. Biliary atresia is a defect in the liver or bile system. Choanal atresia is a defect of the nasal passages (choana). Anal atresia (imperforate anus) and esophageal atresia are defects of the digestive tract. Tricuspid atresia, pulmonary atresia, and aortic atresia involve valves in the heart.. ...
Nasopharyngeal stenosis (NPS) is a pathologic condition in which there is a narrowing within the nasopharynx caudal to the choanae, resulting in variable degrees of inspiratory stertor. This can occur as a congenital anomaly similar to choanal atresia, or secondary to an inflammatory condition (chronic rhinitis or aspiration rhinitis from regurgitation), surgery, or secondary to a space-occupying lesion. Nasopharyngeal stenosis has only been described in a small number of cases in the veterinary literature. It is seemingly more common in cats than dogs. In cats this condition is most commonly associated with chronic rhinitis or a congenital deformity, and in dogs it is most commonly associated with aspiration rhinitis.1-4. The diagnosis of NPS is most easily made via the use of retroflex rhinoscopy. The endoscope is passed through the mouth into the caudal oropharynx then retroflexed dorsally over the soft palate to allow visualization of the nasopharynx and choanae. With NPS a narrow opening ...
The reported incidence of CHARGE Syndrome ranges from 0.1 to 1.2/10,000 and depends primarily on professional recognition. It is not known to be related to any illness, exposure to drugs or alcohol intake during pregnancy, and typically it does not occur to more than one person in a family. It is very rare, and cannot be predicted. Coloboma mainly affects the retina. Major and minor congenital heart defects (commonest cyanotic heart defect is tetralogy of Fallot) occur in 75 80% of patients. Choanal atresia may be membranous or bony, bilateral or unilateral, and is present in 50 60 percent of cases. Mental retardation (ranging from minimal to profound retardation) is another common feature. Under-development of external genitalia is a common finding in males but is less apparent in females. Ear abnormalities include classical finding of unusually shaped ears and hearing loss (conductive and/or nerve deafness resulting mild to severe deafness).. The cause of CHARGE is not known. Mutations in CHD7 ...

CHARGE association is a non-random collection of congenital anomalies. The condition is becoming more widely known to medical and educational professionals. The number of children diagnosed is increasing, probably because of the greater awareness of this condition. This paper considers some of the long-term management problems which are often deferred in the early months, when acute life threatening problems take priority. Questionnaires were sent to parents via the CHARGE Association Family Support Group, UK. Thirty-nine were returned and incomplete information was sought by personal contact or telephone. The majority of children were known professionally to one or both authors and information was therefore checked from medical and educational notes. There is still widespread misunderstanding about the impact of multiple disability, especially when this includes multi-sensory impairment, on the early development of the child. Therefore, the information collected from the study has been from an ...

The etiology of CHARGE syndrome was unknown. We identified twin girls with CHARGE syndrome and a de novo apparently balanced chromosome translocation 46,XX,t(8;13)(q11.2;q22). By mapping the chromosome translocation breakpoints we found that the gene chromodomain-helicase-DNA-binding protein 7 (CHD7) located at 8q12 was disrupted in these girls. CHD7 has a genomic length of 188kb with 9000 coding bases over 37 exons. It has a putative function as a transcription factor which makes it a good candidate gene for a condition which affects multiple body systems ...

Parents of children with CHARGE should be encouraged to become IN CHARGE and very active advocates for their children in order to ensure that an educational program is made that will allow each child to reach their full potential. All children regardless of their final cognitive abilities will require special support in schools to ensure that they maximize their potentials and develop into the most productive people that they can be. In an educational setting all involved must be aware of the special needs a child with CHARGE may have. Teachers of children with CHARGE Syndrome have to be aware of all areas affected by the disease. Because CHARGE can affect the eyes, ears, and brain it is most important that all members of the educational team (teacher of the deaf and hard of hearing, teachers of the visually impaired, audiologists, pediatricians, parents, etc.) Taking each of these into account is vital to the success of the child and family in an educational setting. ...

Dr. Kim Blake is a professor of Pediatrics at Dalhousie University in Nova Scotia, Canada. She has been researching in CHARGE syndrome over the last 35 years and has published extensively. She has answered research questions concerning post-operative airway events, sleep apnea, bone health, cranial nerve abnormalities and gastrointestinal issues. In the last 10 years Dr. Blake has partnered with Dr. Jason Berman and they have developed a zebra-fish-model of CHARGE syndrome to answer further research questions. ...
CHARGE is a rare condition that can affect different parts of the body. The most common problems are with the eyes, ears, heart, nasal passages, feeding and growth - although the condition, and its severity, does vary from person to person.. The name CHARGE was first used in 1981 to refer to a newly recognised cluster of features seen in a number of children. Over the years, it has become clear that CHARGE is a Syndrome and at least one gene causing CHARGE Syndrome has been discovered. The letters in CHARGE were originally used to describe some of the typical features of the syndrome as follows:. Coloboma of the eye, (This is an eye deformity where part of the eye has failed to develop properly and is missing) Heart Defects, Atresia of the choanae, (This is a closure of one, or both, of the openings at the back of the nose.) Delay of growth and/or development, Genital and/or urinary abnormalities, and Ear Abnormalities and deafness. It estimated that 4 - 6% of the deafblind population are ...
This gene encodes a protein containing two chromodomains and an ATP-binding helicase domain that functions as a regulator of transcription. Mutations in this gene result in an array of development defects, including inner ear problems. Mice defective for this gene exhibit many of the clinical features of the CHARGE syndrome caused by mutations in the homologous gene in human. [provided by RefSeq, Sep 2015 ...

We showed, using the murine LLC model, that systemically delivered recombinant VEGI-192 exhibited potent inhibitory activity on tumor formation as well as tumor growth. In one experiment, we treated the animals by i.p. injection with recombinant VEGI at the time when the cancer cells were implanted. Marked inhibition of tumor formation was observed with the treated group. In another experiment, we allowed the tumor to reach about 5% of the body weight before the animals were treated. A substantially retarded growth of the tumors was observed for the treated group during the ∼1-week period following the treatment compared with the tumor growth rate of the untreated group. This result is highly significant because similar inhibition of tumor growth was obtained when VEGI was injected directly into the base of the tumors, suggesting that the effect of VEGI was systemic. Furthermore, there was a significant improvement of the survival time of the tumor-bearing animals resulting from VEGI ...
Objective:. The objectives of this study are to 1) define ocular and systemic associations in a cohort of well-phenotyped participants with uveal coloboma, 2) define risk factors and microforms of coloboma in relatives of affected individuals and 3) establish a repository of DNA and/or lymphoblastoid cell lines from participants with uveal coloboma and their relatives for use in laboratory investigations.. Study Population:. Six hundred (600) individuals of at least one year of age with documented uveal coloboma and their relatives will be enrolled.. Design:. This is a natural history/genetic repository study. Six hundred (600) participants will be enrolled over fifteen years. Participants will undergo a complete age-appropriate baseline eye examination and physical examination and provide a blood, buccal cell/saliva, or DNA sample.. Outcome Measures:. The tests, data, and samples collected will be analyzed to better understand the genetics of uveal coloboma. In particular, ocular and systemic ...
All organs in the body originate from relatively simple structures in the embryo. For example a simple epithelial tube, the neural tube, develops into the highly complex brain. The many forces and growth factors that act upon embryonic tissues are precisely coordinated to shape the morphogenesis of more complex structures. We are interested in understanding how signalling centres are established in the embryo and how signalling pathways are regulated during development. Current research projects in the lab primarily focus on the fibroblast growth factor (FGF) signalling pathway and our aim is to elucidate how deregulated FGF signalling results in birth defects and cellular malfunction. We are particulalrly interested in understanding the functions of the Sprouty genes, which encode FGF antagonists, Tbx1, a T-box transcription factor implicated in DiGeorge syndrome and Chd7, a chromatin remodeller, mutated in CHARGE syndrome. We are studying the role of these genes in the development of the ...
Almost all children with CHARGE Syndrome have ear abnormalities. Many will have deformed outer ears that appear cupped. Middle and inner ear abnormalities occur frequently as well. In about 80-85% of children, hearing loss is prevalent. Establishing and maintaining balance may be a problem for some children.. Children with CHARGE syndrome usually have a number of different abnormalities. In addition to the findings that give the conditions its name, there are other problems that can frequently be seen in individuals with CHARGE syndrome. Some of these include postnatal growth problems, cleft lip and/or palate, immunity problems, facial paralysis, seizures, difficulties swallowing, abnormalities of the pituitary gland, tracheoesophageal fistula (an abnormal connection between the trachea or wind pipe and the esophagus or food pipe), and tracheosophageal atresia (the esophagus ends in a pouch instead of connecting to the stomach).. Once the major medical problems have been addressed, there can be ...

The Senses Australia Girls Club was formed to foster friendships among young women with Deafblindness, while learning skills of hair and makeup. The purpose of the group was to bring together a group of young women with Deafblindness, and develop social skills over a shared activity. Participants in the group experience significant isolation in their everyday lives, some finding true friendship for the first time as young adults. These young women all have additional developmental disabilities, including CHARGE syndrome and epilepsy, requiring specialised support to meet the complexity of their learning needs. The intention of the Girls Club was to further support building of connections among the group of friends, while participating in an age appropriate activity, therefore reducing the experience of isolation felt by these young women ...
