Since brain histamine as a neurotransmitter regulates a number of neurophysiological functions, emphasis has been placed on the development of drugs to target histamine regulation. Yoshikawa et al. explores how the C314T, A939G, G179A, and T632C polymorphisms all impact HNMT enzymatic activity and the pathogenesis of various neurological disorders.
