Ontology: CHARGE Syndrome (C0265354)

Definition (MSH) Rare disease characterized by COLOBOMA; CHOANAL ATRESIA; and abnormal SEMICIRCULAR CANALS. Mutations in CHD7 protein resulting in disturbed neural crest development are associated with CHARGE Syndrome.
Definition (NCI) A rare autosomal dominant syndrome usually caused by mutations in the CHD7 gene. The term CHARGE is an acronym for the following unusual congenital abnormalities that are associated with this syndrome: coloboma of the eye, heart defects, choanal atresia, growth and developmental retardation, genital, and ear abnormalities.
