Target Data

Function 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.; FUNCTION
Gene References into Functions
  1. Goodpasture antigen peptide alpha3127-148 was identified as a mutual T and B cell epitope in patients with anti-glomerular basement membrane disease. PMID: 28152559
  2. Results showed that COL4A4 c.1471C>T and COL4A3 c.3418 + 1G>T variants in cis are pathogenic and co-segregate with the benign familial hematuria. This result suggests that COL4A3 and COL4A4 digenic mutations in cis mimicking an autosomal dominant inheritance should be considered as a novel inheritance pattern of benign familial hematuria. PMID: 29742505
  3. In a large Spanish family with Alport sysndrome, carriers of certain mutations in the COL4A3 gene were more severely affected and had earlier onset of the disease compared to non-carriers of these mutations. PMID: 29089023
  4. For mutation screening, all exons of COL4A3 and COL4A4 genes were polymerase chain reaction-amplified and direct sequenced from genomic DNA, and the mutations were analyzed by comparing with members in this family, 100 ethnicitymatched controls and the sequence of COL4A3 and COL4A4 genes from GenBank. A novel mutation determining a nucleotide change was found, i.e. c.4195 A>T (p.Met1399Leu) at 44th exon of COL4A4 gene. PMID: 28674241
  5. Two families showed COL4A3/A4 mutations in cis, mimicking an autosomal dominant inheritance with a more severe phenotype and one showed COL4A3/A4 mutations in trans, mimicking an autosomal recessive inheritance with a less severe phenotype. In a fourth family, a de novo mutation (COL4A5) combined with an inherited mutation (COL4A3) triggered a more severe phenotype PMID: 27859054
  6. Alport syndrome is the result of mutations in any of three type IV collagen genes, COL4A3, COL4A4, or COL4A5. Because the three collagen chains form heterotrimers, there is an absence of all three proteins in the basement membranes where they are expressed. (Review) PMID: 27576055
  7. These findings indicate that the heterozygous mutations in COL4A3 or COL4A4 may cause ESRD on their own, although secondary factors, such as environmental factors or unknown genetic changes, might also contribute to the phenotype of kidney disease in patients with ADAS. PMID: 27281700
  8. This study indicates that in our population, the COL4A3 rs55703767 polymorphism decreased the risk of KC. However, the TIMP-1 rs6609533 polymorphism was associated with an increased risk of KC. PMID: 28197741

  19. A new mutation in the COL4A3 gene responsible for autosomal dominant Alport syndrome, which only generates hearing loss in some carriers PMID: 25450602

  24. Release of recombinant tumstatin in transgenic platelet granules led to antiangiogenic effect of platelets. PMID: 24655355
  25. COL4A3 overexpression in podocytes caused chain retention in the endoplasmic reticulum associated with activation of the unfolded protein response. Mutant COL4A3 chains differentially activated the UPR pathway in human and transfected mouse cells. PMID: 24262798
