Human Research Studies

CADD: Center for Antisocial Drug Dependence: Genetics: This Center was funded to study genetic influences on, and treatment of, antisocial drug dependence, under a NIDA (DA 11015) grant. We represent a collaborative effort across two campuses of the University of Colorado, and the expertise of four research organisations.

Colorado Adoption Project: The purpose of the CAP is to study both nature and nurture, to determine the genetic predispositions as well as the environmental influences that contribute to traits such as intelligence, personality, and behavior.

COTWINS: The primary purpose of COTWINS is to use new technologies to understand adolescents, their development, and behavior.

Colorado Twin Registry: The Colorado Twin Registry (CTR) is a population based registry housed at the Institute for Behavioral Genetics. Recruitment has been ongoing since 1968. Four samples construct the CTR: the Community Twin Sample (CTS), Infant Twin Sample (ITS), Longitudinal Twin Sample (LTS), and the Early Reading Development Sample (ERDS).

Specific Twin Studies: Summaries and links to current research studies we are conducting with twins and their families, categorized by study.

Studies of Executive Cognitive Functioning: Two twin studies at IBG are exploring the role of Executive Cognitive Functions (ECFs) as they relate to human development and behavior.

National Youth Survey Family Study: Started in 1976, this study has surveyed individuals representative of the national population to look at their changing attitudes, beliefs and behaviors about topics such as career goals, involvement with community and family, attitudes about violence, drugs, and social values.

The National Longitudinal Study of Adolescent Health (AddHealth): Add Health is a nationally representative study that explores the causes of health-related behaviors of adolescents in grades 7 through 12 and their outcomes in young adulthood. AddHealth seeks to examine how social contexts (families, friends, peers, schools, neighborhoods, and communities) influence adolescents' health and risk behaviors.

Colorado Learning Disabilities Research Center: Since 1973, researchers of the Colorado Learning Disabilities Research Center (CLDRC) have been conducting research pertaining to the definition, etiology, and treatment of learning disabilities (LD) and attention-deficit/hyperactivity disorder (ADHD).

Genotyping Lab: We currently have several protocols available on-line, including IBG-Hvar1 & IBG-Hvar2, Serotonin Transporter Linked Polymorphic region, Dopamine D4 Receptor, Dopamine Transporter and Monoamine Oxidase A upstream VNTR.

Statistical Genetics Lab: We are using large, publicly available single nucleotide polymorphism datasets to elucidate the genetic architecture of complex traits, such as schizophrenia, bipolar disorder, body mass index, and height.

Variance Componence Models for Mapping QTLs: Software access and information about QTK mapping.

Northern Camaroon Language and Genes Project: The overall aim of the NCLGP is to explore the correlation between related languages and the genetic relationships of the Northern Cameroonian populations that speak them
