APOE and insomnia measurement: Accounting for correction, there was a genome-wide significant local genetic correlation between AD and SRPs at three regions (chr16:29036613-31382943 harboring previous AD locus GDPD3 for AD with insomnia and snoring; chr19:4348967-5811852 harboring previous AD locus APOE for AD and insomnia; and chr2:201576284-202818637 harboring previous migraine locus CDK15 for AD and sleep duration) using SUPERGNOVA (PSuperGnova < 1.0 × 10–4).
