Mapping Personality Traits to Genes

Completed

Conditions studied: Mental Disorder

In brief

Previous research involving families, twins, and adoption all support the idea that there is a substantial heritable aspect to personality. The goal of this research study is to determine how genetics influence heritable personality traits. The work will focus on how genetics affect the chemical messengers which brain cells use to communicate with each other (neurotransmitters). The study involves collecting personality data and DNA samples from related individuals, primarily male siblings and female siblings, but also including parents. Genetic tests performed on these samples will continue to focus on variations in genes, which potentially effect brain neurotransmission. This research has the potential to advance knowledge of genetic influences on human behavior that may be relevant both to normal personality and to psychopathology.
