Condition 101 About C Syndrome

What is the definition of C Syndrome?

C syndrome, also known as Opitz trigonocephaly syndrome, is characterized by trigonocephaly, severe intellectual disability, hypotonia, variable cardiac defects, redundant (extra folds of) skin, joint and limb abnormalities, and unusual facial features such as upslanted palpebral fissures (upward pointing outside corners of the eyes), epicanthal folds, depressed nasal bridge, and low-set, posteriorly rotated ears. This condition is genetically heterogeneous, meaning that there is evidence of more than one type of inheritance. While many cases are sporadic, autosomal recessive, autosomal dominant, and germline mosaicism have all been suggested. At least some cases of C syndrome have been caused by dysfunction of the CD96 gene.
