gene encoding a protein crucial for skin and hair integrity
COL17A1 is a gene that encodes for a protein called collagen type XVII, alpha 1. This protein is crucial for the structural integrity of the skin, as it helps anchor the outer layer of the skin (epidermis) to the underlying layer (dermis). Mutations in the COL17A1 gene can lead to skin disorders and hair loss conditions, such as epidermolysis bullosa and certain types of alopecia.
