We examined whether the most significantly associated variant for fast beta EEG was an expression quantitative trait locus (eQTL) in the UK Brain Expression Consortium (BRAINEAC; http://www.braineac.org/). Braineac draws on data from 134 neuropathologically normal individuals of European ancestry and assesses 10 different regions of the brain (Table 3).43 Only the single SNP most associated with fast beta EEG was examined in Braineac to minimize multiple testing. Further, a Bonferonni correction was applied to all P-values. Associations that withstood multiple testing were examined in the Genotype-Tissue Expression Project (GTEx) database (www.gtexportal.org) to confirm eQTL findings.
