BACKGROUND: The Catechol-O-methyltransferase (COMT) gene contains a functional polymorphism, Val158Met, that has been found to influence human pain perception. In one study fibromyalgia was less likely among those with Val/Val genotype.

METHODS: In the 1995-97 Nord-Trøndelag Health Study (HUNT), the association between Val/Met polymorphism at the COMT gene and chronic musculoskeletal complaints (MSCs) was evaluated in a random sample of 3017 individuals.

RESULTS: The distribution of the COMT Val158Met genotypes and alleles were similar between controls and the twelve different chronic MSCs groups. Even when the Met/Met and Val/Met genotypes were pooled, the distribution of the Val/Val genotype and other genotypes were similar between controls and the chronic MSCs groups.

CONCLUSION: In this population-based study, no significant association was found between Val/Met polymorphism at the COMT gene and chronic MSCs.
