Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 1P and 3B. PP2BP4_ModerateBS1_Supporting

The NM_002241.5(KCNJ10):​c.1124G>A​(p.Arg375His) variant causes a missense change. The variant allele was found at a frequency of 0.0000192 in 1,612,868 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R375C) has been classified as Uncertain significance.

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 -2 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.
BP4
Computational evidence support a benign effect (MetaRNN=0.13331708).
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000199 (29/1460560) while in subpopulation AMR AF = 0.000157 (7/44658). AF 95% confidence interval is 0.0000729. There are 0 homozygotes in GnomAdExome4. There are 14 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
