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 asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 5 of the SLC12A1 protein (p.Asn5Ser). This variant is present in population databases (rs376723001, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SLC12A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1911168). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
