Genes affected
SLC12A1 (HGNC:10910): (solute carrier family 12 member 1) This gene encodes a kidney-specific sodium-potassium-chloride cotransporter that is expressed on the luminal membrane of renal epithelial cells of the thick ascending limb of Henle's loop and the macula densa. It plays a key role in concentrating urine and accounts for most of the NaCl resorption. It is sensitive to such diuretics as furosemide and bumetanide. Some Bartter-like syndromes result from defects in this gene. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional splice variants have been described but their biological validity in humans has not been experimentally proven.[provided by RefSeq, May 2010]

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 257 of the SLC12A1 protein (p.Gly257Ser). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with Bartter syndrome type 1 (PMID: 17998760, 18391953, 28893421). In at least one individual the variant was observed to be de novo. This variant is also known as g788a. ClinVar contains an entry for this variant (Variation ID: 548675). 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 SLC12A1 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
