Genes affected

SLC12A5 (HGNC:13818): (solute carrier family 12 member 5) K-Cl cotransporters are proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The protein encoded by this gene is an integral membrane K-Cl cotransporter that can function in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Sep 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 20-46022971-GGAGGAAGAGGAGGAGGAGGAA-G is Benign according to our data. Variant chr20-46022971-GGAGGAAGAGGAGGAGGAGGAA-G is described in ClinVar as [Benign]. Clinvar id is 1686325.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00643 (900/139924) while in subpopulation NFE AF= 0.00962 (614/63818). AF 95% confidence interval is 0.00899. There are 3 homozygotes in gnomad4. There are 432 alleles in male gnomad4 subpopulation. Median coverage is 19. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
