Review Study-Gene Influence on Hazardous Criminal Behaviors

Increased criminality over the globe has led researchers to focus on the various happenings of criminal behavior. The scientific rationale for reduced control of inhibiting antisocial impulses and aggressive behavior, that goes with a variant of the relevant gene such as MAO-A is underactive prefrontal cortex area of the brain. The current study explores past reviews regarding gene expression in criminal behavior. The purpose of this study is to develop an awareness of gene expression in criminal behavior. A literature review conducted using electronic databases for this study, reviewing 30 articles from the year 1970 to 2018. The articles reviewed focused on genetic variation in human aggression, MAOA genotype, and aggression, MAOA promoter activity, a gene (MAOA) predicting behavioral aggression. The study concludes that although MAOA is a promoter of various activity variations, in MAOA can lead to hazardous criminal behaviour. The depth of understanding in this area would bring insights into professionals to rehabilitate criminals on a humanitarian base. The current study suggests there are limited studies in this area, especially in developing countries, thus the government and non-governmental agencies should encourage more researches in this area, which would bring more insight into this area.
