Abstract:

Although antisocial behavior is a complex condition with environmental and genetic etiologies, the single susceptibility gene such as the Monoamine oxidase A (MAOA) gene, the serotonin transporter promoter gene (5-HTT) and the catechol O-methyltransferase gene, can’t completely interpret the molecular genetics mechanism of the antisocial behavior. The genome-wide association study (GWAS) methodology from molecular genetics views millions of large number of single nucleotide polymorphisms (SNPs) and copy number variation (CNVs) as genetic markers to search the genetic locus related to external phenotype on the level of entire genome by high-throughput genotyping technology and so it can provide important clues for the further understanding of hereditary factors of antisocial behavior.In order to achieve the analysis for the gene-psychology-environment mechanism of complex traits or behavior, future studies should combine the accurate genotyping techniques with mental and environment factors.

Key words: antisocial behavior, molecular genetics mechanism, genome-wide association study
