3C syndrome, also known as CCC dysplasia, Craniocerebellocardiac dysplasia[1] or Ritscher–Schinzel syndrome,[2] is a rare condition, whose symptoms include heart defects, cerebellar hypoplasia, and cranial dysmorphism. It was first described in the medical literature in 1987 by Ritscher and Schinzel, for whom the disorder is sometimes named.
