Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_033380.3(COL4A5):c.1258G>A(p.Gly420Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G420V) has been classified as Pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 22, 2023 | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 420 of the COL4A5 protein (p.Gly420Arg). 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: 32647767; Invitae). ClinVar contains an entry for this variant (Variation ID: 447199). 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 COL4A5 protein function. This variant disrupts the p.Gly420 amino acid residue in COL4A5. Other variant(s) that disrupt this residue have been observed in individuals with COL4A5-related conditions (PMID: 8940267, 9848783, 32647767), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. - |
