Balanced t(6;8)(6p8p;6q8q) and the CHARGE association

Abstract

A girl is described with bilateral retinal colobomata, Fallot's tetralogy, unilateral choanal atresia, abnormalities of the external ears, bilateral sensorineural deafness, a unilateral facial nerve palsy, and a tracheo-oesophageal fistula. A clinical diagnosis of the CHARGE association was made. She had an apparently balanced whole arm translocation involving chromosomes 6 and 8. Parental karyotypes were normal.
