GABRA1 and epilepsy: Even though the GABRA1 rs2279020 was associated with an increased risk of epilepsy among studies without HWE under heterozygous comparison (OR = 1.83, 95% CI, 1.30–2.58) and dominant genetic model (OR = 1.52, 95% CI, 1.13–2.03), the polymorphism was not associated with the risk of epilepsy among studies with HWE in controls (Table 2, Figure 2A).
