Entrez Gene Summary for COL4A5 Gene

  • 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. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Aug 2010]

GeneCards Summary for COL4A5 Gene

COL4A5 (Collagen, Type IV, Alpha 5) is a Protein Coding gene. Diseases associated with COL4A5 include alport syndrome and alport syndrome and thin basement membrane nephropathy. Among its related pathways are PI3K-Akt signaling pathway and Signaling by FGFR. GO annotations related to this gene include extracellular matrix structural constituent.

Disorders for COL4A5 Gene

(1) OMIM Diseases for COL4A5 Gene (303630)


  • Alport syndrome, X-linked (APSX) [MIM:301050]: A syndrome that is characterized by progressive glomerulonephritis, renal failure, sensorineural deafness, specific eye abnormalities (lenticonous and macular flecks), and glomerular basement membrane defects. The disorder shows considerable heterogeneity in that families differ in the age of end-stage renal disease and the occurrence of deafness. {ECO:0000269 PubMed:10094548, ECO:0000269 PubMed:10561141, ECO:0000269 PubMed:10563487, ECO:0000269 PubMed:10684360, ECO:0000269 PubMed:10862091, ECO:0000269 PubMed:11004279, ECO:0000269 PubMed:11223851, ECO:0000269 PubMed:1352287, ECO:0000269 PubMed:1363780, ECO:0000269 PubMed:1376965, ECO:0000269 PubMed:1672282, ECO:0000269 PubMed:24522658, ECO:0000269 PubMed:7599631, ECO:0000269 PubMed:7853788, ECO:0000269 PubMed:8406498, ECO:0000269 PubMed:8651292, ECO:0000269 PubMed:8651296, ECO:0000269 PubMed:8829632, ECO:0000269 PubMed:8940267, ECO:0000269 PubMed:9150741, ECO:0000269 PubMed:9452056, ECO:0000269 PubMed:9848783}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Deletions covering the N-terminal regions of COL4A5 and COL4A6, which are localized in a head-to-head manner, are found in the chromosome Xq22.3 centromeric deletion syndrome. This results in a phenotype with features of diffuse leiomyomatosis and Alport syndrome (DL-ATS).
