Invitae RCV001377080 SCV001574313 likely pathogenic not provided 2020-03-19 criteria provided, single submitter clinical testing Glycine residues within the Gly-Xaa-Yaa repeats of the triple helix domain are required for the structure and stability of fibrillar collagens (PMID: 7695699, 8218237, 19344236). In COL4A5, missense variants at these glycine residues are significantly enriched in individuals with disease (PMID: 23720012, 27627812) compared to the general population (ExAC). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant has not been reported in the literature in individuals with COL4A5-related conditions. ClinVar contains an entry for this variant (Variation ID: 522498). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with aspartic acid at codon 236 of the COL4A5 protein (p.Gly236Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid.
