Disease

CO6A3_HUMAN Defects in COL6A3 are a cause of Bethlem myopathy (BM) [MIM:158810. BM is a rare autosomal dominant proximal myopathy characterized by early childhood onset (complete penetrance by the age of 5) and joint contractures most frequently affecting the elbows and ankles.^[1] ^[2] ^[3] ^[4] ^[5] Defects in COL6A3 are a cause of Ullrich congenital muscular dystrophy (UCMD) [MIM:254090; also known as Ullrich scleroatonic muscular dystrophy. UCMD is an autosomal recessive congenital myopathy characterized by muscle weakness and multiple joint contractures, generally noted at birth or early infancy. The clinical course is more severe than in Bethlem myopathy.^[6] ^[7]

Function

CO6A3_HUMAN Collagen VI acts as a cell-binding protein.
