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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC12A5. . Gene score misZ 4.7022 (greater than the threshold 3.09). Trascript score misZ 5.953 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy, 34, malignant migrating partial seizures of infancy, developmental and epileptic encephalopathy, epilepsy, idiopathic generalized, susceptibility to, 14.

BP4

Computational evidence support a benign effect (MetaRNN=0.10731614).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000203 (28/1381146) while in subpopulation MID AF= 0.00131 (6/4566). AF 95% confidence interval is 0.000572. There are 0 homozygotes in gnomad4_exome. There are 15 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
