Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP2BP4_Strong

The NM_001126108.2(SLC12A3):c.1706C>T(p.Ala569Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000222 in 1,614,220 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A569E) has been classified as Uncertain significance.

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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 138 curated pathogenic missense variants (we use a threshold of 10). The gene has 18 curated benign missense variants. Gene score misZ: -0.93606 (below the threshold of 3.09). Trascript score misZ: 0.71313 (below the threshold of 3.09). GenCC associations: The gene is linked to Gitelman syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.055492252).
