COMT Gene's Role in Pain Modulation for Women with Migraine

Research Summary

A study in the International Journal of Molecular Sciences explored the impact of the COMT Val158Met polymorphism on pain modulation in women with migraine. Researchers examined 70 women each with chronic migraine, episodic migraine, and no pain. They assessed pain thresholds and the influence of the Val158Met genotype on conditioned pain modulation (CPM). Findings showed significant interactions for pain thresholds at the temporalis and lateral epicondyle and for cold and heat pain thresholds, but not at the tibialis anterior. Women with the Met/Met genotype and chronic migraine had reduced CPM, particularly in the trigeminal area, unlike healthy controls.
