COL17A1 wt Allele

**Semantic type:** Gene or Genome

**Definition:** Human COL17A1 wild-type allele is located in the vicinity of 10q25.1 and is approximately 55 kb in length. This allele, which encodes collagen alpha-1(XVII) chain protein, is involved in hemidesmosome formation and keratinocyte adhesion. Mutation of the gene and immunoreactivity during revertant mosaicism is associated with both generalized atrophic benign and junctional epidermolysis bullosa. Mutations in the gene are also associated with epithelial recurrent erosion dystrophy.
