background:
EVC2 is an integral membrane protein that plays a vital role in bone formation and skeletal development. Defects in EVC2 are a cause of Ellis-van Creveld syndrome (EVC), also known as chondroectodermal dysplasia. EVC is an autosomal recessive disorder 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.
Function:
Positive regulator of the hedgehog signaling pathway. Plays a critical role in bone formation and skeletal development.
Subunit:
Interacts with EVC.
Subcellular Location:
Cell membrane; Single-pass type I membrane protein. Cytoplasm, cytoskeleton, cilium basal body. Cell projection, cilium. Cell projection, cilium membrane. Nucleus.
Tissue Specificity:
Found in the heart, placenta, lung, liver, skeletal muscle, kidney and pancreas.
DISEASE:
Defects in EVC2 are a cause of Ellis-van Creveld syndrome (EVC) [MIM:225500]; also known as chondroectodermal dysplasia. EVC is an autosomal recessive disorder 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.
Defects in EVC2 are a cause of acrofacial dysostosis Weyers type (WAD) [MIM:193530]; also known as Curry-Hall syndrome. Acrofacial dysostoses are a heterogeneous group of disorders combining limb defects with facial abnormalities. WAD is an autosomal dominant disorder characterized by dysplastic nails, postaxial polydactyly, acrofacial dysostosis, short limbs and short stature. The phenotype is milder than Ellis-van Creveld syndrome.
