GABRG2 protein which is a crucial part of GABA receptor encoded by the gamma-aminobutyric acid A receptor, gamma 2 (GABRG2) gene. The exonic GABRG2 rs211037 gene polymorphism has been commonly explore with respect to variable association to different types of epilepsies (all types, IGE and FS) and AEDs response. The current meta-analysis study was designed to explore whether the GABARG2 C588 T (rs211037) genetic variant predicts susceptibility to different types epilepsy and pharmacoresistance to AEDs. Twenty studies were included, contained 3351 epileptic patients and 3649 controls in meta-analysis, for the association GABRG2 rs211037 polymorphism with susceptibility to different types of epilepsy. Similarly, five studies comprised of 632 responder patients and 401 non-responder patients in meta-analysis, were selected for the evaluation of the GABRG2 rs211037 polymorphism to pharmacoresistance to AEDs. Meta-analysis was performed separately for FS and IGE in Asian and Caucasian population for association to epilepsies and pharmacoresistance to AEDs but pharmacoresistance to AEDs in FS and IGE was not performed in Asian and Caucasian due to limited number of studies. Meta-analysis showed a significant link between GABRG2 rs211037 polymorphism and susceptibility to all types of epilepsies in total Population in (CC vs CT, OR 1.03, 95% CI 0.0–1.2, p = 0.0006 and CC vs TT, OR 0.03, 95% CI 0.8–1.2, p = 0.01) genetic models. Similarly, a significant association of this polymorphisms with all types of epilepsy was found with Asian population in genetic models of CC vs CT( OR 0.86 (0.7-1.0,p=0.11), CC vs TT (OR 0.67 (0.5-0.9, p=0.000), but CC vs CT+TT genetic model shows the association of all types of epilepsies in Asian as well Caucasian population ( OR 0.6 (0.5-0.7), p=0.001 and OR 1.05 (0.9-1.2), p=0.000). Similarly, CC vs CT, CC vs TT and CC vs CT+TT genetic models were also associated with IGE and FS epilepsies in total population, Asian and Caucasian population. The alleles also showed a significant association with epilepsy. Genetic models of CC vs CT, CC vs TT and CC vs CT+TT were also associated with pharmacoresistance to AEDs (P<0.05) in total population, Asian and Caucasian population. The publication bias was not significant (P<0.05) but the heterogenicity (I2%) was mostly more than 50%. FS, caused by two studies with small sample sizes, however the possibility of false positive results because of significant studies for FS cannot be excluded. This study showed a significant association of GABRG2 rs211037 polymorphism with susceptibility to different types of epilepsies and pharmacoresistance to AEDs in all population. Future studies with larger sample sizes from different population are suggested to verify the results.
