Description

The missense variant p.G893D in COL4A5 (NM_000495.5) has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.G893D variant is novel (not in any individuals) in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The gene COL4A5 contains 202 pathogenic missense variants, indicating that missense variants are a common mechanism of disease in this gene. The p.G893D missense variant is predicted to be damaging by both SIFT and PolyPhen2. The nucleotide c.2678 in COL4A5 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
