Deletion of proximal 6q: a clinical report and review of the literature.

We report on a 13-year-old boy who had an interstitial deletion of the long arm of chromosome 6[46,XY,del(6)(pter----q13::q15----qter)]. A characteristic facial appearance with facial asymmetry, vertebral anomalies, valgus heels with flat feet, and congenital heart defect seem to form part of a specific del 6q syndrome.
