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: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_001126108.2
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.
PP5
Variant 16-56913293-G-A is Pathogenic according to our data. Variant chr16-56913293-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 448395.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
