Entrez Gene Summary for COL7A1 Gene

  • 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]

GeneCards Summary for COL7A1 Gene

COL7A1 (Collagen Type VII Alpha 1 Chain) is a Protein Coding gene. Diseases associated with COL7A1 include Epidermolysis Bullosa, Pretibial and Epidermolysis Bullosa Dystrophica, Ar. Among its related pathways are Collagen chain trimerization and Phospholipase-C Pathway. GO annotations related to this gene include identical protein binding and serine-type endopeptidase inhibitor activity. An important paralog of this gene is COL12A1.

UniProtKB/Swiss-Prot for COL7A1 Gene

  • Stratified squamous epithelial basement membrane protein that forms anchoring fibrils which may contribute to epithelial basement membrane organization and adherence by interacting with extracellular matrix (ECM) proteins such as type IV collagen.

  • Epidermolysis bullosa dystrophica, with subcorneal cleavage (EBDSC) [MIM:131750]: A bullous skin disorder with variable sized clefts just beneath the level of the stratum corneum. Clinical features include blisters, milia, atrophic scarring, nail dystrophy, and oral and conjunctival involvement, as seen in dystrophic epidermolysis bullosa. {ECO:0000269 PubMed:11874498, ECO:0000269 PubMed:2653224}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Epidermolysis bullosa pruriginosa (EBP) [MIM:604129]: A distinct clinical subtype of epidermolysis bullosa dystrophica. It is characterized by skin fragility, blistering, scar formation, intense pruritus and excoriated prurigo nodules. Onset is in early childhood, but in some cases is delayed until the second or third decade of life. Inheritance can be autosomal dominant or recessive. {ECO:0000269 PubMed:10383749, ECO:0000269 PubMed:11142768}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Nail disorder, non-syndromic congenital, 8 (NDNC8) [MIM:607523]: A nail disorder characterized by isolated toenail dystrophy. The nail changes are most severe in the great toes and consist of the nail plate being buried in the nail bed with a deformed and narrow free edge. {ECO:0000269 PubMed:11843659}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Epidermolysis bullosa acquisita (EBA) is an autoimmune acquired blistering skin disease resulting from autoantibodies to type VII collagen.
  • Transient bullous dermolysis of the newborn (TBDN) [MIM:131705]: TBDN is a neonatal form of dystrophic epidermolysis bullosa characterized by sub-epidermal blisters, reduced or abnormal anchoring fibrils at the dermo-epidermal junction, and electron-dense inclusions in keratinocytes. TBDN heals spontaneously or strongly improves within the first months and years of life. {ECO:0000269 PubMed:9856844}. Note=The disease is caused by mutations affecting the gene represented in this entry.
