Definition:

Cardio-facio-cutaneous (CFC) syndrome is a congenital disorder characterized by short stature, a characteristic face, cardiac defects, developmental delay and mental retardation. Affected individuals present with ectodermal abnormalities such as sparse, friable hair, hyperkeratotic skin lesions and a generalized ichthyosis-like condition. Typical facial characteristics include high forehead, down-slanting palpebral fissures, a depressed nasal bridge, and posteriorly angulated ears. CFC can be caused by mutations in BRAF, KRAS, MEK1, and MEK2, encoding components of the RAS-MAPK pathway.
