We identified, for the first time, associations of the rs841 (guanosine triphosphate cyclohydrolase 1 gene) and rs2097903 (catechol-O-methyltransferase gene) SNPs with higher risk of fibromyalgia susceptibility.

Functional pain syndromes, such as fibromyalgia and temporomandibular disorder, are associated with enhanced catecholamine tone and decreased levels of catechol-O-methyltransferase (COMT; an enzyme that metabolizes catecholamines).

Our results suggest that the Val158Met COMT polymorphism modulated some psychological variables but not pressure pain sensitivity in FMS, because women carrying the Met/Met genotype show higher disability, depression, and anxiety but similar PPTs than those with Val/Met or Val/Val genotypes.

Further, the findings advance our understanding of the role of COMT in FM, suggesting that genetic variation in the val(158)met polymorphism may affect FM pain through pathways of pain-related cognition.
