RCV000498195 | SCV000589315 | pathogenic | not provided | 2017-06-09 | criteria provided, single submitter | clinical testing | The G227S variant in the COL4A5 gene has previously been reported in at least one individual with Alport syndrome (Hashimura et al., 2014). This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The G227S variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species, and is located within the triple helical region in a G-X-Y motif (Uniprot). In silico analysis predicts this variant is probably damaging to the protein structure/function. Based on currently available evidence, we consider G227S to be pathogenic. |
