Collagen, type IV, alpha 5 (Alport syndrome), also known as COL4A5, is a human gene.

section_title =
summary_text = This gene encodes one of the six subunits of type IV collagen, the major structural component of basement membranes. Mutations in this gene are associated with X-linked Alport syndrome, also known as hereditary nephritis. Like the other members of the type IV collagen gene family, this gene is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter. Three transcript variants have been identified for this gene. [cite web | title = Entrez Gene: COL4A5 collagen, type IV, alpha 5 (Alport syndrome)| url =| accessdate = ]
