Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM1PP2PP3_ModeratePP5

The NM_002241.5(KCNJ10):​c.179T>C​(p.Ile60Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,210 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I60V) 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_pathogenic. The variant received 6 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_002241.5
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.901
PP5
Variant 1-160042354-A-G is Pathogenic according to our data. Variant chr1-160042354-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 205826.
