The purpose of this study was to investigate the possible association between childhood epilepsy and KCNJ10 gene polymorphisms (rs61822012 and rs2486253). A total of 200 epileptic cases and 200 healthy controls enrolled to this study. Genomic DNAs from the patients and control cases were analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism methods. 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). T allele was also increased in patients with generalized tonic-clonic seizures (P = .0158). However, no statistically significant association was found between rs61822012 polymorphism and epilepsy. Our data suggest that G/T genotype of the KCNJ10 gene rs2486253 polymorphism affects risk for development of common types of childhood epilepsy. The T allele of this polymorphism was found to be a seizure-susceptibility allele for tonic-clonic epilepsy.
