The effect of catechol‐O‐methyltransferase polymorphisms on pain is modified by depressive symptoms
AssociationN=3,904Schwahn C. et al.(2012)· European Journal of Pain

This population-based study of 3,904 subjects examined the interaction between COMT and TXNRD2 SNPs and temporomandibular disorder (TMD) pain, modified by depressive symptoms. Six SNPs from the first COMT/TXNRD2 haploblock showed significant interactions with depressive symptoms (smallest p-value: 2.7 × 10^-10), with opposite SNP effects between depressed and non-depressed individuals. In non-depressed subjects, rs5993882 (COMT) was most associated with TMD pain, while in depressed subjects, rs1544325 (COMT) and TXNRD2 SNPs were preferentially associated. The findings indicate that COMT polymorphisms affect pain perception through a mechanism significantly moderated by depressive symptoms.

About COMT

Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters. In addition to its role in the metabolism of endogenous substances, COMT is important in the metabolism of catechol drugs used in the treatment of hypertension, asthma, and Parkinson disease. COMT is found in two forms in tissues, a soluble form (S-COMT) and a membrane-bound form (MB-COMT). The differences between S-COMT and MB-COMT reside within the N-termini. Several transcript variants are formed through the use of alternative translation initiation sites and promoters. [provided by RefSeq, Sep 2008]
