Description : The 3C syndrome, also known as Ritscher-Schinzel syndrome, is a developmental malformation
syndrome characterized by craniofacial abnormalities, congenital heart defects, and
cerebellar brain malformations. Facial features include prominent occiput, prominent
forehead, low-set ears, downslanting palpebral fissures, depressed nasal bridge, and
micrognathia. Cardiac defects can include septal defects and aortic stenosis, among
others, and brain imaging shows Dandy-Walker malformation, cerebellar vermis hypoplasia,
posterior fossa cysts, and ventricular dilatation. Affected individuals have severe
developmental delay (summary by Leonardi et al., 2001; Seidahmed et al., 2011).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the KIAA0196 gene (KIAA0196, 610657.0004);
