Multiple genome‐wide association studies identified noncoding single‐nucleotide polymorphisms in GABRA2 associated with increased risk for epilepsy (International League Against Epilepsy Consortium on Complex Epilepsies, 2014, 2018), as well as alcohol dependence and brain oscillations (Edenberg et al., 2004; Strac et al., 2015). The gene discussed is GABRA2; the disease is epilepsy.
