Oculodentodigital dysplasia (ODDD) is caused by mutations in the GJA1 gene, which encodes Gap junction alpha-1 protein also known as connexin-43. The majority of cases are autosomal dominant (MIM 164200), but ODDD can also be autosomal recessive (MIM 257850). ODDD is characterized by abnormalities of the face, eyes, dentination, and digits of hands and feet.read more
