Abstract

OBJECTIVE:

To investigate the association between single nucleotide polymorphisms (SNPs) of casein kinase I gamma 2 (CSNK1G2) gene and children with familial febrile convulsions.

METHODS:

The study samples were collected from unrelated Chinese Han population of Hebei province, including a cohort of 53 children with familial febrile convulsions(FC) and a control cohort of 101 individuals. Genotypes of SNPs rs2074882, rs740423, rs2277737, rs4806825, rs1059684 were typed by polymerase chain reaction-restriction fragment length polymorphism.

RESULTS:

The frequencies of the five SNPs complied well with the Hardy-Weinberg equilibrium in FC group and normal group. The distribution of genotype and frequencies of alleles of the SNPs rs740423, rs2277737, rs1059684 in familial febrile convulsions group was significantly different from that in control group. No significant difference was observed in the distribution of genotypes and frequencies of alleles at SNP rs2074882 between two groups. Analysis on rs4806825 was not made owing to its less allele frequency.

CONCLUSION:

These data indicate that SNPs rs740423, rs2277737, rs1059684 of CSNK1G2 gene may contribute to familial febrile convulsions in children.
