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]

SLC12A1-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesOct 25, 2023The SLC12A1 c.50A>G variant is predicted to result in the amino acid substitution p.Asn17Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.044% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/15-48499966-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.50A>G (p.N17S) alteration is located in exon 2 (coding exon 1) of the SLC12A1 gene. This alteration results from a A to G substitution at nucleotide position 50, causing the asparagine (N) at amino acid position 17 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
