title: Subtypes of ADH2 gene in alcoholics.
abstract: Alocholism is the multifactorial disease influenced by genetic environmental interaction and genetic variation of the genes may be associated with alcohol dependence due to its modified function in behavioral and physiological responses. In the present study, genetic variation was detected in the subtypes of gene, coding for the alcohol metabolizing enzyme Alcohol Dehydrogenase 2 (ADH2). Blood samples were collected from the alcoholic and non alcoholic subjects and genotyping was performed using PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism), analysis to determine genetic polymorphisms in the ADH2 gene subtypes. The three subtypes of ADH2 gene (ADH2.1, ADH2.2 and ADH2.3) were found in both alcoholics (Family History Positive and Family History Negative) as well as non alcoholics.
