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 leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 272 of the SLC12A3 protein (p.Leu272Pro). This variant is present in population databases (rs568513106, gnomAD 0.004%). This missense change has been observed in individuals with Gitelman syndrome (PMID: 18391953, 31398183). ClinVar contains an entry for this variant (Variation ID: 209191). 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%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

Variant summary: SLC12A3 c.815T>C (p.Leu272Pro) results in a non-conservative amino acid change located in the Amino acid permease/ SLC12A domain (IPR004841) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 251392 control chromosomes (gnomAD). c.815T>C has been reported in the literature in multiple compound heterozygous individuals affected with Gitelman syndrome (Ji_2008, Glaudemans_2011, Peng_2017, Zhang_2023). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 22009145, 18391953, 28700713, 21415153, 36806220). Three submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
