Using SNPs, COGA researchers have studied several candidate genes that may contribute to the development of alcohol and/or nicotine dependence, most prominently genes encoding parts of the receptors through which the brain chemical (i.e., neurotransmitter) gamma-aminobutyric acid (GABA) acts on its target cells.
