Genetic Studies in Addiction
Both alcohol- and drug-addicted subjects as well as healthy controls will be asked to participate in this study. only one study visit will be required of participants and during this visit, 2 and [1/2]) tablespoons of blood will be collected. Plasma samples for Dna will be coded and immediately sent to the eugene McDermott Center for Growth and Development at university of Texas Southwestern Medical Center. Samples will have their Dna banked in a secure freezer with coded identification. When a large enough number of samples have been acquired, candidate genes have been suitably refined, and SnP chips become commercially available, appropriate pathways and candidate genes will be assessed via SnP chips and associated with previously assessed behaviors, personality styles, and/or biologic responses.
