Collagen alpha-1(X) chain is a protein that in humans is a member of the collagen family encoded by the COL10A1 gene.[1][2]

This gene encodes the alpha chain of type X collagen, a short chain collagen expressed by hypertrophic chondrocytes during endochondral ossification. Unlike type VIII collagen, the other short chain collagen, type X collagen is a homotrimer. Mutations in this gene are associated with Schmid type metaphyseal chondrodysplasia (SMCD) and Japanese type spondylometaphyseal dysplasia (SMD).[2]

DDR2 is a collagen receptor for it.[3]

Recent studies into the early detection of colon cancer have identified COL10A1 protein levels in serum as a potential diagnostic biomarker candidate to detect both adenoma lesions and tumor.[4]
