TET2, TET31, CHST112, L-dopa, GPC33, CTNNBIP12, dopamine, GPC43, SORCS21,2, PPP2R5E, CRY12, BDNF, NGF, NGFR, HTT1,2, ARHGAP262,4, KLF5	17 (9 Molecules associated with aggressive-behaviour from GWAS-SNPs results)

The Gene Symbol in “Bold” indicates that the gene was significantly associated with aggression behaviour traits. “1” indicates that the gene was associated with T1 aggressive-behaviour phenotype; “2” indicates that the gene was associated with T2 aggressive-behaviour phenotype; “3” indicates that the gene was associated with T3 aggressive-behaviour phenotype; “4” indicates that the gene was associated with T4 aggressive-behaviour phenotype.
