Collagen alpha-3(IX) chain is a protein that in humans is encoded by the COL9A3 gene.[1][2][3]

Function

This gene encodes one of the three alpha chains of type IX collagen, the major collagen component of hyaline cartilage. Type IX collagen, a heterotrimeric molecule, is usually found in tissues containing type II collagen, a fibrillar collagen. Mutations in this gene are associated with multiple epiphyseal dysplasia.[3]
