The frequency of rs1053074 G allele was lower in the childhood absence epilepsy (CAE) group than that in the healthy controls (28.4% vs 36.2%, p = 0.01, OR = 0.70[0.53-0.93]).
The frequency of rs12729701 G allele and AG+GG genotypes was lower in the CAE group than that in the healthy controls (21.2% vs 28.4%, p = 0.01, OR = 0.74[0.59-0.94] and 36.3% vs 48.1%, p = 0.01, OR = 0.83[0.72-0.96], respectively).
These results demonstrated that KCNJ10 (rs1186689) polymorphisms was correlated with ASD susceptibility in Chinese Han children, and the abnormal expression of Kir2.1 and Kir4.1 in ASD model rats suggested a mechanism by which Kir channels may play a role in ASD.
Analysis of the SNPs after stratification based on CC clinical stage and subtype revealed that rs1048512, rs6659346, rs217727, rs9931702, and rs9302648 were associated with CC risk in clinical stages I-II; rs2862833, rs2732044, rs1030389, and rs1045935 were associated with CC risk in clinical stages III-IV; and rs217727, rs9931702, and rs9302648 were associated with CC risk in squamous carcinomas.

It was also observed that the variant, p.Arg271Cys in KCNJ10, previously thought to have a protective effect against seizure susceptibility, was found in a patient with Pendred syndrome with co-existing epilepsy.
Association analysis of the human KCNJ10 gene identified a common KCNJ10 missense variation (Arg271Cys) that influences susceptibility to focal and generalized epilepsies.
There were significant associations between the G/T genotype of KCNJ10 gene rs2486253 polymorphism in the idiopathic generalized epilepsy group (P = .037) and in subjects with generalized tonic-clonic seizures (P = .0015).
We identified two heterozygous KCNJ10 mutations (p.R18Q and p.V84M) in three children (two unrelated families) with seizures, ASD, and intellectual disability.

Intriguingly, the metabolic alkalosis present in patients carrying the R65P mutation possibly improves residual function of KCNJ10, which shows higher activity at alkaline pH.
