The work will focus on how genetics affect the chemical messengers which brain cells use to communicate with each other (neurotransmitters).\n\nThe 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.\n\nThis research has the potential to advance knowledge of genetic influences on human behavior that may be relevant both to normal personality and to psychopathology.", "detailedDescription"=>"Building on family, twin and adoption studies suggesting that substantial aspects of personality are heritable, research under this protocol explores potential genetic influences on normal personality dimensions. We have previously reported associations between variation in neurotransmitter system genes and variation in personality traits, both across and within families, in a sample of the general population. This 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 affect brain neurotransmission. In some cases, participants are recontacted to specifically investigate whether identified variations in neurotransmitter system genes actually affect neurotransmission. Large population samples are needed in this research, particularly since a new epidemiologically standard population sample will be obtained. 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."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD", "ADULT", "OLDER_ADULT"], "healthyVolunteers"=>true, "eligibilityCriteria"=>"Personality data and DNA samples will be collected from related individuals, primarily pairs of male and pairs of female siblings, but also including parents."}, "identificationModule"=>{"nctId"=>"NCT00001414", "briefTitle"=>"Mapping Personality Traits to Genes", "organization"=>{"class"=>"NIH", "fullName"=>"National Institutes of Health Clinical Center (CC)"}, "officialTitle"=>"Mapping Personality Traits to Genes", "orgStudyIdInfo"=>{"id"=>"940122"}, "secondaryIdInfos"=>[{"id"=>"94-M-0122"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"20892", "city"=>"Bethesda", "state"=>"Maryland", "country"=>"United States", "facility"=>"National Institute of Mental Health (NIMH)", "geoPoint"=>{"lat"=>38.98067, "lon"=>-77.10026}}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Institute of Mental Health (NIMH)", "class"=>"NIH"}}}}
