Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate

The NM_000338.3(SLC12A1):c.1614T>A(p.Tyr538Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000685 in 1,460,128 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. Y538Y) has been classified as Benign. Variant results in nonsense mediated mRNA decay.

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 creates a premature translational stop signal (p.Tyr538*) in the SLC12A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC12A1 are known to be pathogenic (PMID: 8640224, 9585600, 19096086). This variant is present in population databases (rs6493311, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with Bartter syndrome (PMID: 27748541). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
