The CHARGE association was first described in 1979 by Hall et al., in 17 children with multiple congenital anomalies who were ascertained by choanal atresia [].In the same year, Hittner reported this syndrome in 10 children with ocular colobomas and multiple congenital anomalies [], hence the syndrome is also called Hall-Hittner syndrome []. A different missense variant was reported in one patient with Kallmann syndrome. The effects of CHARGE syndrome are different for each person, and most often, there is no family history of CHARGE.
