Research identifying a specific gene in the transmission of a vulnerability to alcoholism has led to speculation that the gene may disrupt the activity of ________ receptors in the brain.

Question

Quizplus · Accepted Answer

The specific gene identified in the transmission of a vulnerability to alcoholism is known as the GABRA2 gene. This gene may disrupt the activity of GABA (gamma-aminobutyric acid) receptors in the brain, which are involved in regulating dopamine release. Dopamine is a neurotransmitter associated with reward and pleasure, and disruptions to dopamine signaling have been implicated in addiction, including alcoholism. Therefore, dopamine receptors are the most likely choice for the missing word in the statement.
