Lack of GABABR1 gene variation (G1465A) in a Chinese population with temporal lobe epilepsy

Summary GABA(B) receptor1 (GABA B R1) gene is one of the susceptibility genes for temporal lobe epilepsy (TLE). Recently, it is reported that the GABA B R1 polymorphism (G1465A) conferred a highly increased susceptibility to TLE. We performed a case-control study to confirm the findings. The study included a total of 112 nonlesional TLE patients and 124 controls of Chinese ancestry. Our study did not show any polymorphism in this locus, and suggested this polymorphism may not be a strong susceptibility factor for TLE among Chinese population.
