![]() ![]() Conclusion: CHARGE syndrome should be considered as a differential diagnosis to detect the mild end of the spectrum, even if the patient does not fit the criteria.Ĭhoanal atresia coloboma CHD7 gene semicircular canal hypoplasia. MLPA analysis of all coding exons of the CHD7 gene revealed no pathogenic deletion/duplication. Behavioural, psychological, cognitive and sleep difficulties are not well delineated and are likely associated with biopsychosocial factors. Results: In the study population, 6 different mutations were detected in 5 patients, and 2 different polymorphisms were detected in the CHD7 gene in 3 patients. CHARGE syndrome (OMIM 214800) is a phenotypically complex genetic condition characterised by multi-system, multi-sensory impairments. Individuals with CHARGE syndrome experience sensory issues including difficulties perceiving balance, experiencing touch, and sensing pressure (Brown, 2005). All patients were tested for karyotype analysis and CHD7 gene mutation/deletion. This article introduces the special topic in the American Journal of Medical Genetics on behavior in individuals with CHARGE syndrome. Cognitive self-regulation allows one to compare alternative choices, stay motivated when thinking about a problem, focus on precision and accuracy, and adapt prior learning to the current problem. Too much cognitive regulation can result in obsession. Many of those requests come from therapists and educators (teachers, clinicians, specialty staff) who may have a student in their classroom or they have a new therapy referral for a client with CHARGE syndrome. A lack of cognitive self-regulation can result in the individual being unfocused. ![]() Materials and methods: Twenty-one patients who had at least one of the major symptoms of CHARGE syndrome (coloboma, choanal atresia, characteristic ear anomalies, semicircular canal hypoplasia, and cranial nerve anomalies) were included in the study. The Foundation gets many requests from a variety of professionals asking for information about CHARGE syndrome. This study aimed to disclose the mild end of the phenotypic spectrum of CHARGE syndrome, which has a highly variable expressivity. Background/aim: CHARGE syndrome is a rare autosomal dominant disease with multiple congenital anomalies and cognitive impairment, which is caused by mutations in the CHD7 gene.
