  • 功能：
    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.

    2. Three collagen type IV alpha 4 chain (COL4A4) heterozygous mutations that lead to 3 different collagen type IV kidney disease phenotypes, manifesting as Thin basement membrane nephropathy (TBMN), autosomal dominant Alport syndrome (ADAS), and focal segmental glomerulosclerosis (FSGS). PMID: 29669314

    5. we describe a novel splicing mutation in COL4A4 that results in TBMN. This analysis increases our understanding of TBMN phenotype-genotype correlations, which should facilitate more accurate diagnosis and prenatal diagnosis of TBMN. PMID: 26833262

    11. COL4A4 related nephropathy caused by novel mutation in a large consanguineous Saudi family. PMID: 24398087
    12. Our findings suggest that variants in the COL4A4 gene may contribute to the development of lattice degeneration of the retina. PMID: 22723992
    13. The absence of pathogenic mutations in COL4A4 gene in our large number of unrelated keratoconus patients indicates that other genetic factors are involved in the development of this disorder PMID: 20664914
    14. COL4A4 mutation: from familial hematuria to autosomal-dominant or recessive Alport syndrome. PMID: 12028435
    15. Six of seven (86%) individuals with autosomal recessive Alport syndrome who had 3 novel COL4A4 mutations in the compound heterozygous or homozygous forms developed renal failure in adulthood, as well as hearing loss and ocular abnormalities. PMID: 12325029
    16. Two stop codons (R1377X and 2788/91delG) and a glycine substitution (G960R) resulted in hematuria. S969X mutation. PMID: 12631110

    20. The molecular analysis demonstrated that the probands were genetic compounds for two different mutations in the COL4A4 gene pinpointing to the correct diagnosis of autosomal recessive ATS. PMID: 16338941
    21. A clinical evaluation of probands and their relatives of the five families carrying mutations in either the COL4A3 or the COL4A4 gene was carried out to underline the natural history of the autosomal recessive ATS. PMID: 16970251
    22. 16 novel mutations identified in COL4A3, COL4A4 & COL4A5 genes in Slovenian families with Alport syndrome & benign familial hematuria (BFH); 4 heterozygous mutations in COL4A4 (2 splice site, 1 in-frame deletion & 1 missense) identified in BFH PMID: 17396119
    23. On the basis of linked-function analysis, we demonstrated that collagen binding domain of MMP2 tuned the cleavage of collagen IV by MMP9, presumably by inducing a ligand-linked structural change on the type IV collagen. PMID: 19109975
    24. It is difficult to make a differential diagnosis with a benign familial haematuria due to heterozygous mutations of COL4A4 and COL4A3, especially in young patients, and with a X-linked form of Alport syndrome in families where only females are affected. PMID: 19129241
