As one of the most heritable traits in humans (Anokhin et al., 2001; Smit, Posthuma, Boomsma, & Geus, 2005; Smit et al., 2006; Tang et al., 2007; Van Beijsterveldt, Molenaar, De Geus, & Boomsma, 1996; Zietsch et al., 2007), EEG oscillations may serve as an intermediate phenotype in the pathway from genes to behavior (de Geus, 2010; Gottesman, & Gould, 2003; Loo et al., 2015). Despite the numerous twin and family studies of the genetics of oscillations, studies linking specific genetic variants such as Single Nucleotide Polymorphisms (SNPs) to oscillation strength remain scarce. The first genome‐wide association study of EEG oscillation strength showed an association between SGIP1 and theta oscillations in both Native American and European Ancestry samples. Two recent studies from the Collaborative Study on the Genetics of Alcoholism (COGA) associated several intergenic SNPs at 6q22 in a European sample (Meyers et al., 2017a), and at 3q26 in African American ancestry (Meyers et al., 2017b) for >20 Hz fast beta oscillations.
