COL4A4 - collagen type IV alpha 4 chain Gene
Also Known as BFH; ATS2; CA44
Species: Homo sapiens
About COL4A4
This gene has 8 transcripts (splice variants), 157 orthologues, 37 paralogues and is associated with 6 phenotypes. Broad expression in kidney (RPKM 5.3), thyroid (RPKM 4.9) and 18 other tissues.
Summary
This gene encodes one of the six subunits of type IV Collagen, the major structural component of basement membranes. This particular Collagen IV subunit, however, is only found in a subset of basement membranes. 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. Mutations in this gene are associated with type II autosomal recessive Alport syndrome (hereditary glomerulonephropathy) and with familial benign hematuria (thin basement membrane disease). Two transcripts, differing only in their transcription start sites, have been identified for this gene and, as is common for Collagen genes, multiple polyadenylation sites are found in the 3' UTR.
