![]() ![]() 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.

CHARGE is an acronym for the common clinical features often associated with. CHARGE Syndrome - Symptoms, Causes, Treatment NORD Learn about CHARGE Syndrome, including symptoms, causes, and treatments. MLPA analysis of all coding exons of the CHD7 gene revealed no pathogenic deletion/duplication. CHARGE Syndrome is a specific set of birth defects that tend to occur together. Results We discuss that CHARGE syndrome is primarily a clinical diagnosis. 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. PMID: 33662639 DOI: 10.1016/j.ejmg.2021.104189 Abstract Although the prognosis of CHARGE syndrome can be highly variable from mild until severe, final diagnosis is difficult to establish in utero. We then further explored the mild end of the phenotypic spectrum of CHD7 mutations. Hearing loss can be very difficult to measure in young children. CHARGE is an acronym that classically describes a syndrome which is comprised of Coloboma, Heart defects, Atresia of the choanae, Retardation of growth and/or development, Genitourinary abnormalities, and Ear anomalies (Pagon, Zonana, & Yong, 1981). The hearing loss can range from a mild hearing loss to profound deafness. All patients were tested for karyotype analysis and CHD7 gene mutation/deletion. CHARGE syndrome is associated with characteristic external ears that tend to protrude and lack lobes. CHARGE syndrome is a rare autosomal dominant disorder, associated with coloboma (C), heart defects (H), choanal atresia (A), retardation of growth and/or central nervous system (R), genitourinary anomalies (G) and ear abnormalities (E). 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. Additional detailed phenotyping revealed a mild external ear defect, an audiogram indicated mild bilateral. This study aimed to disclose the mild end of the phenotypic spectrum of CHARGE syndrome, which has a highly variable expressivity. He was found to harbor a de novo CHD7 RSV (p.Y1412D). 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. ![]()
