Genetic and environmental contributions to risk for disordered gambling

Abstract

The literature on the behavioral genetics of disordered gambling is reviewed in this chapter. This includes studies that have focused on estimating the aggregate influence of genetic and environmental factors and studies that have focused on identifying the specific genes that account for the aggregate genetic risk. Topics also covered are disordered gambling comorbidity, developmentally relevant studies, identifying the specific environments that account for the aggregate environmental risk, and gene-environment interplay. The chapter is concluded with a summary of the general conclusions, areas in need of more research, and recommendations for the way forward.
