Summaries for Cardiofaciocutaneous Syndrome 2

UniProtKB/Swiss-Prot : 73 Cardiofaciocutaneous syndrome 2: A form of cardiofaciocutaneous syndrome, a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects and mental retardation. Heart defects include pulmonic stenosis, atrial septal defects and hypertrophic cardiomyopathy. Some affected individuals present with ectodermal abnormalities such as sparse, friable hair, hyperkeratotic skin lesions and a generalized ichthyosis-like condition. Typical facial features are similar to Noonan syndrome. They include high forehead with bitemporal constriction, hypoplastic supraorbital ridges, downslanting palpebral fissures, a depressed nasal bridge, and posteriorly angulated ears with prominent helices. CFC2 patients often do not have the skin abnormalities, such as ichthyosis, hyperkeratosis, and hemangioma observed in CFC1.

MalaCards based summary : Cardiofaciocutaneous Syndrome 2, is also known as cfc2. An important gene associated with Cardiofaciocutaneous Syndrome 2 is KRAS (KRAS Proto-Oncogene, GTPase). Affiliated tissues include skin, heart and bone, and related phenotypes are low-set ears and ptosis

Disease Ontology : 12 A cardiofaciocutaneous syndrome that has material basis in heterozygous mutation in KRAS on chromosome 12p12.1.

OMIM : 56 Cardiofaciocutaneous (CFC) syndrome is a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects, and mental retardation (summary by Niihori et al., 2006). In a phenotypic comparison of BRAF (164757)-positive and KRAS-positive individuals with CFC, Niihori et al. (2006) observed that patients with KRAS mutations did not have the skin abnormalities, such as ichthyosis, hyperkeratosis, and hemangioma, that were present in patients with BRAF mutation. (615278)
