Labcorp Genetics (formerly Invitae), Labcorp	RCV001886034	SCV002139872	pathogenic	not provided	2024-03-07	criteria provided, single submitter	clinical testing	This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 738 of the SLC12A3 protein (p.Leu738Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Gitelman syndrome (PMID: 9734597, 17159356). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 1376627). 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 SLC12A3 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
