Genes affected

KCNJ10 (HGNC:6256): (potassium inwardly rectifying channel subfamily J member 10) This gene encodes a member of the inward rectifier-type potassium channel family, characterized by having a greater tendency to allow potassium to flow into, rather than out of, a cell. The encoded protein may form a heterodimer with another potassium channel protein and may be responsible for the potassium buffering action of glial cells in the brain. Mutations in this gene have been associated with seizure susceptibility of common idiopathic generalized epilepsy syndromes. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 14 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Trascript score misZ: 2.7053 (below the threshold of 3.09). GenCC associations: The gene is linked to EAST syndrome, enlarged vestibular aqueduct syndrome, Pendred syndrome.

BP6

Variant 1-160042228-G-A is Benign according to our data. Variant chr1-160042228-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 411158.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000092 (14/152108) while in subpopulation AFR AF = 0.000266 (11/41416). AF 95% confidence interval is 0.000149. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
