Homo sapiens

Also known as EBD1; EBR1; EBDCT; NDNC8

Gene ID: 1294 | Gene type: protein coding

About COL7A1

Cytogenetic location: 3p21.31 Genomic coordinates (GRCh38): 3:48,564,073-48,595,329 (from NCBI)

This gene has 11 transcripts (splice variants), 51 orthologues, 37 paralogues and is associated with 21 phenotypes. Biased expression in skin (RPKM 63.4), endometrium (RPKM 13.0) and 5 other tissues.

Summary

This gene encodes the alpha chain of type VII collagen. The type VII collagen fibril, composed of three identical alpha collagen chains, is restricted to the basement zone beneath stratified squamous epithelia. It functions as an anchoring fibril between the external epithelia and the underlying stroma. Mutations in this gene are associated with all forms of dystrophic epidermolysis bullosa. In the absence of mutations, however, an acquired form of this disease can result from an autoimmune response made to type VII collagen. [provided by RefSeq, Jul 2008]
