For SNPs, the direction of effect refers to allele 1 (see Supplementary Table S3), allele 2 has the opposite effect.

multiallelic association (all STR alleles)

biallelic association (presence/absence of the BV677278 deletion)

q-values were calculated by the Benjamini and Hochberg method of False Discovery Rate (FDR) correction for multiple testing with 1472 hypotheses of imaging-genetic associations performed. Those in bold reached or trended toward statistical significance after FDR correction for multiple testing.
