Structural highlights
Disease
[CO4A5_HUMAN] X-linked diffuse leiomyomatosis - Alport syndrome;X-linked Alport syndrome. The disease is caused by mutations affecting the gene represented in this entry. 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).
Function
[CO4A5_HUMAN] Type IV collagen is the major structural component of glomerular basement membranes (GBM), forming a 'chicken-wire' meshwork together with laminins, proteoglycans and entactin/nidogen.
