The sex-specific signals were supported by a large number of suggestive SNPs, which were in incomplete LD with the lead SNP (See regional association plots, Figure S1B). Imputation quality for the lead SNPs was high (average r2 = 99.7, 93.8 and 86.8) for rs41456347, rs2764450 and rs11215217, respectively. Gene-based and gene-set analyses yielded no significant genes (top gene= CENPI, p= 3.2 × 10-5, Table S3a-c, Figure S3) or gene-sets (top gene-set=‘Reactome cell communication’, p= 3.6 × 10-4, Table S3d). None of the traditional candidate genes on antisocial behaviour were significantly associated with ASB (top gene=TH, pcorr=.0841, Table S4a-c).
