Genes affected

KCNJ1 (HGNC:6255): (potassium inwardly rectifying channel subfamily J member 1) Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. It is activated by internal ATP and probably plays an important role in potassium homeostasis. The encoded protein has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Mutations in this gene have been associated with antenatal Bartter syndrome, which is characterized by salt wasting, hypokalemic alkalosis, hypercalciuria, and low blood pressure. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.49).

BP6

Variant 11-128840064-G-A is Benign according to our data. Variant chr11-128840064-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 376831.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.

BP7

Synonymous conserved (PhyloP=3.21 with no splicing effect.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000749 (114/152282) while in subpopulation AMR AF = 0.00745 (114/15302). AF 95% confidence interval is 0.00634. There are 3 homozygotes in GnomAd4. There are 90 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position FAILED quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
