Genes affected

SLC12A3 (HGNC:10912): (solute carrier family 12 member 3) This gene encodes a renal thiazide-sensitive sodium-chloride cotransporter that is important for electrolyte homeostasis. This cotransporter mediates sodium and chloride reabsorption in the distal convoluted tubule. Mutations in this gene cause Gitelman syndrome, a disease similar to Bartter's syndrome, that is characterized by hypokalemic alkalosis combined with hypomagnesemia, low urinary calcium, and increased renin activity associated with normal blood pressure. This cotransporter is the target for thiazide diuretics that are used for treating high blood pressure. Multiple transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1018 of the SLC12A3 protein (p.Arg1018Gln). This variant is present in population databases (rs370175770, gnomAD 0.008%). This missense change has been observed in individual(s) with Gitelman syndrome (PMID: 17511264, 21415153, 22009145, 23328711). 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: 594235). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt SLC12A3 protein function with a positive predictive value of 95%. This variant disrupts the p.Arg1018 amino acid residue in SLC12A3. Other variant(s) that disrupt this residue have been observed in individuals with SLC12A3-related conditions (PMID: 23328711), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -
