| Abstrakt: | Background: Juvenile myoclonic epilepsy (JME) is an idiopathic generalized epilepsy syndrome with genetic basis and accounts for 10% of all forms of epilepsy. Despite the existence of rare mutations responsible for some familial forms inherited in a Mendelian pattern, the genetics of JME is complex and probably involves multiple genes. Because of widespread distribution in the central nervous system (CNS) and their ability to produce postsynaptic inhibition, GABA (A) receptor subunits (GABRs) encoding genes represent high ranking candidates for epilepsy susceptibility. Aim: This case/control study was designed to investigate whether the rs211037 of the GABRG2 gene is a risk factor for JME in the Brazilian population. Materials and Methods: The polymorphism was genotyped in 98 patients and 130 controls using polymerase chain reaction-restriction fragment length polymorphism method. Descriptive and statistical analyses were performed using SNP stat software. Results: Genotype proportions and allele frequencies for the rs211037 polymorphism of the GABARG2 gene did not differ significantly between the groups, even when the odds ratio was adjusted for clinical variables. Conclusion: These results present no evidence for an association of rs211037 with JME. Further studies are required to investigate the involvement of the GABRG2 gene in the genetic susceptibility to this epileptic syndrome. |
