Role of GABRA2 in Trajectories of Externalizing Behavior Across Development and Evidence of Moderation by Parental Monitoring

Abstract
Considerable advances in genetics at the level of understanding the structure of the human genome and associated diversity as well as in genotyping and analysis methods, have ushered in an era where identifying genes underlying complex disorders is no longer a distant possibility.1 The number of articles published regarding such associations is rapidly escalating, and associations are replicating across independent samples. The growth of genomewide association studies and large consortia of researchers who are pooling data to create more powerful gene-finding samples only promises to continue this trend.2,3
