Involvement in diseasei

Ellis-van Creveld syndrome (EVC) [MIM:225500]: An autosomal recessive condition characterized by the clinical tetrad of chondrodystrophy, polydactyly, ectodermal dysplasia and cardiac anomalies. Patients manifest short-limb dwarfism, short ribs, postaxial polydactyly, and dysplastic nails and teeth. Congenital heart defects, most commonly an atrioventricular septal defect, are observed in 60% of affected individuals.
Note: The disease is caused by mutations affecting the gene represented in this entry.2 Publications

Acrofacial dysostosis, Weyers type (WAD) [MIM:193530]: An autosomal dominant condition characterized by dysplastic nails, postaxial polydactyly, dental anomalies, short limbs, short stature and normal intelligence. The phenotype is milder than Ellis-van Creveld syndrome.
Note: The disease is caused by mutations affecting the gene represented in this entry.
