Preferred Label : C syndrome;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Opitz trigonocephaly syndrome; Trigonocephaly syndrome;
Description : The C syndrome, also known as Opitz trigonocephaly syndrome, is a malformation syndrome
characterized by trigonocephaly, severe mental retardation, hypotonia, variable cardiac
defects, redundant skin, and dysmorphic facial features, including upslanted palpebral
fissures, epicanthal folds, depressed nasal bridge, and low-set, posteriorly rotated
ears (summary by Kaname et al., 2007). C syndrome shows phenotypic overlap with Bohring-Opitz
syndrome, or C-like syndrome (605039), a disorder with more severe features than C
syndrome, caused by heterozygous mutation in the ASXL1 gene (612990) on chromosome
20q11.;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the CD96 gene (CD96, 606037.0001);
