ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association between two single nucleotide polymorphisms (SNPs), rs9390754 and rs4840200, in the glutamate receptor 2 (GRIK2) gene and the genetic susceptibility to epilepsy (EP) in the Han population in Central China.</p><p><b>METHODS</b>A case-control study was performed in 284 EP children (including 132 children with refractory epilepsy) and 315 normal children from Central China. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the genotypes of the two SNPs rs9390754 and rs4840200. The genotype frequency was compared between groups.</p><p><b>RESULTS</b>The frequencies of GG, GA, and AA genotypes of SNP rs9390754 showed a significant difference between the EP and normal control groups (P=0.016). The allele frequency also showed a significant difference between the two groups (P=0.002). The frequencies of CC, CT, and TT genotypes of SNP rs4840200 and allele frequency showed no significant differences between the two groups. The C allele frequency of SNP rs4840200 in the refractory EP subgroup was significantly higher than in the non-refractory EP subgroup (OR=1.435, 95% CI 1.021-2.016, P=0.037).</p><p><b>CONCLUSIONS</b>In the Han population in Central China, the polymorphisms of SNP rs9390754 in the GRIK2 gene may be associated with EP susceptibility, and the C allele of SNP rs4840200 may be a genetic risk factor for the development of drug resistance in children with EP.</p>
