CHARGE syndrome

CHARGE syndrome is a rare, usually sporadic disorder with multiple congenital anomalies. CHARGE is an acronym for the six prevalent clinical features of the disease, namely, coloboma, heart defect, atresia of choanae, retardation of growth and development, genital hypoplasia, and ear anomalies/deafness. Abnormal semicircular canals, arhinencephaly, and rhombencephalic dysfunctions are also considered as important features. Nearly 2/3 of cases harbor mutations within the CHD7 gene.
