B.D. Hall first described the CHARGE association in a 1979 journal paper of about 17 children who had been born with choanal atresia.[1] During the same year, H.M. Hittner described 10 children who had choanal atresia as well as coloboma, congenital heart defect, and hearing loss.[2] Using both coloboma or choanal atresia and some of the other related characteristic malformations, R. A. Pagon first coined the acronym CHARGE in 1981 to emphasize that this cluster of associated malformations occurred together.[3] It came to be recognised as a syndrome within the umbrella of the CHARGE association, a set of apparently random signs occurring together. Since the signs seen in CHARGE are caused by a genetic anomaly, its name was eventually changed to 'CHARGE syndrome'.[citation needed]
