Position is in hg19/GRCh37.
Key: cDNA, complementary DNA; CI, confidence interval; Corr, corrected p-value, p-value after Bonferroni correction (p-value∗ 40 [number of variants considered in the single-variant association test]); ExAC, Exome Aggregation Consortium; MA, minor allele; MAF, minor allele frequency; ExAC, Exome Aggregation Consortium; OR, odds ratio.
MAF cases-controls reported a Belgian cohort = 4.66%–6.27% (Cuyvers et al., 2015).
MAF in ExAC (European non-Finnish) = 6.14% and MAF in EVS (European American) = 6.24%.
