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.

Computational evidence support a benign effect (BayesDel_noAF=-0.4).

BP6

Variant 16-56879598-C-A is Benign according to our data. Variant chr16-56879598-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 255878.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.96 with no splicing effect.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00139 (2032/1461554) while in subpopulation EAS AF = 0.0172 (684/39700). AF 95% confidence interval is 0.0162. There are 29 homozygotes in GnomAdExome4. There are 941 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 29 AR gene
