receptor activity (pBH = 3.35 × 10-9), GABA-A receptor activity (pBH = 7.38 × 10-8), and neurotransmitter binding (pBH = 7.38 × 10-8) in the category of "Molecular Function"; and postsynaptic membrane (pBH = 1.86 × 10-7), chloride channel complex (pBH = 2.76 × 10-7), and synapse part (pBH = 3.36 × 10-7) in the category of "Cellular Component". Many of these enriched functional categories are consistent with the current knowledge of alcohol dependence and ethanol response [24]. These indicate that the top ranked genes are highly enriched in functions relevant to alcoholism.
