During the past decade a wealth of information on alcohol consumption has been obtained from human and model organism studies, but rarely have data from different studies been integrated to form a comprehensive blueprint of the genetic networks that contribute to alcohol drinking. In future, studies integrating data on alcohol-related phenotypes from GWASs and transcriptional profiling studies on both humans and model organisms will make it possible to construct biologically meaningful networks of genes that contribute to alcohol consumption and dependence, and generate a deeper understanding of the genetic susceptibility for alcoholism.
