Labcorp Genetics (formerly Invitae), Labcorp RCV000809019 SCV000949155 pathogenic not provided 2023-12-21 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 90 of the SLC12A3 protein (p.His90Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Gitelman syndrome (PMID: 15687331, 22679066, 26770037). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 653275). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SLC12A3 protein function. This variant disrupts the p.His90 amino acid residue in SLC12A3. Other variant(s) that disrupt this residue have been observed in individuals with SLC12A3-related conditions (PMID: 24825090), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
