Heavy drinking can cause chronic hypertension, possibly due to effects on the autonomic nervous system. Catechol- O-methyltransferase (COMT) inactivates catecholamines, and a G to A substitution in codon 108 in the soluble COMT mRNA (or codon 158 in the membrane-bound form) substitutes methionine for valine and alters enzyme activity.
