Labcorp Genetics (formerly Invitae), Labcorp RCV002512553 SCV003442043 pathogenic not provided 2024-02-20 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 353 of the P2RX2 protein (p.Gly353Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with autosomal dominant deafness (PMID: 24211385). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 155763). 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 P2RX2 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects P2RX2 function (PMID: 31636190). For these reasons, this variant has been classified as Pathogenic.
