Associations for PCCB and STX17 were all replicated in FinnGen, of which the genetically predicted high level expressions were positively associated with AF risk (OR 1.05, 95% CI 1.01–1.10; OR 1.16, 95% CI 1.06–1.27, respectively, Supplementary Table S5). Here, PCCB is linked to atrial fibrillation.
