Gene information for COL9A1 (Homo sapiens)
(Information is obtained from NCBI Gene database)
Entrez gene ID1297
Official gene symbolCOL9A1
Full namecollagen, type IX, alpha 1
Aliases,DJ149L1.1.2,EDM6,FLJ40263,MED,
Gene summaryThis gene encodes one of the three alpha chains of type IX collagen, which is a minor (5-20%) collagen component of hyaline cartilage. Type IX collagen is usually found in tissues containing type II collagen, a fibrillar collagen. Studies in knockout mice have shown that synthesis of the alpha 1 chain is essential for assembly of type IX collagen molecules, a heterotrimeric molecule, and that lack of type IX collagen is associated with early onset osteoarthritis. Mutations in this gene are associated with osteoarthritis in humans, with multiple epiphyseal dysplasia, 6, a form of chondrodysplasia, and with Stickler syndrome, a disease characterized by ophthalmic, orofacial, articular, and auditory defects. Two transcript variants that encode different isoforms have been identified for this gene. [provided by RefSeq]
