Invitae	RCV000710841	SCV001236856	pathogenic	not provided	2024-01-15	criteria provided, single submitter	clinical testing	This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 897 of the COL4A4 protein (p.Gly897Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of Alport syndrome (PMID: 8787673, 26809805). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 17406). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt COL4A4 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
