Collagen alpha-1(XII) chain is a protein that in humans is encoded by the COL12A1 gene.^[5]^[6]

This gene encodes the alpha chain of type XII collagen, a member of the FACIT (fibril-associated collagens with interrupted triple helices) collagen family. Type XII collagen is a homotrimer found in association with type I collagen, an association that is thought to modify the interactions between collagen I fibrils and the surrounding matrix.

Alternatively spliced transcript variants encoding different isoforms have been identified.^[6]

Clinical significance

Mutations in COL12A1 are known to cause the following conditions:

Bethlem myopathy 2 (also known as Ehlers-Danlos syndrome myopathic type)^[7];
Ullrich congenital muscular dystrophy 2^[7].

Collagen, type I, alpha 1, also known as alpha-1 type I collagen, is a protein that in humans is encoded by the COL1A1 gene. COL1A1 encodes the major component of type I collagen, the fibrillar collagen found in most connective tissues, including cartilage.

Collagen alpha-2(XI) chain is a protein that in humans is encoded by the COL11A2 gene.

FACIT collagen is a type of collagen and also a proteoglycan that have two or more triple-helical domains that connect to collagen fibrils and share protein domains with non-collagen matrix molecules. FACIT collagens derive their name from their association and interaction with fibrillar collagens. Unlike fibrillar collagens, which form long fibers.

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

Collagen alpha-3(VI) chain is a protein that in humans is encoded by the COL6A3 gene. This protein is an alpha chain of type VI collagen that aids in microfibril formation. As part of type VI collagen, this protein has been implicated in Bethlem myopathy, Ullrich congenital muscular dystrophy (UCMD), and other diseases related to muscle and connective tissue.
