Gene Gene information from NCBI Gene database.
Entrez ID 1296
Gene name Collagen type VIII alpha 2 chain
Gene symbol COL8A2
Synonyms (NCBI Gene)
FECDFECD1PPCDPPCD2
Chromosome 1
Chromosome location 1p34.3
Summary This gene encodes the alpha 2 chain of type VIII collagen. This protein is a major component of the basement membrane of the corneal endothelium and forms homo- or heterotrimers with alpha 1 (VIII) type collagens. Defects in this gene are associated with
