A heterozygous missense variant, NM_000091.4(COL4A3):c.4793T>G, has been identified in exon 51 of 52 of the COL4A3 gene. The variant is predicted to result in a major amino acid change from leucine to arginine at position 1598 of the protein (NP_000082.2(COL4A3):p.(Leu1598Arg)). The leucine residue at this position has very high conservation (100 vertebrates, UCSC), and is located within the C4 domain. In silico predictions for this variant are consistently pathogenic (Polyphen, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD database at a frequency of 0.005% (0 homozygotes). This variant has not been previously reported in clinical cases. Based on the information available at the time of curation, this variant has been classified as VARIANT of UNCERTAIN SIGNIFICANCE (VUS).
