Also Known as MED; EDM2; STL5; DJ39G22.4

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 1298

About COL9A2

Cytogenetic location: 1p34.2 Genomic coordinates (GRCh38): 1:40,300,489-40,317,286 (from NCBI)

This gene has 12 transcripts (splice variants), 151 orthologues, 37 paralogues and is associated with 6 phenotypes. Broad expression in prostate (RPKM 5.8), brain (RPKM 5.5) and 20 other tissues.

Summary

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. This chain is unusual in that, unlike the Other two type IX alpha chains, it contains a covalently attached glycosaminoglycan side chain. Mutations in this gene are associated with multiple epiphyseal dysplasia. [provided by RefSeq, Jul 2008]
