Large-Scale Genetic Study Links Fibromyalgia to Neurological Pathways and Unexpected Gene

An analysis of 2.5 million people’s DNA, published in Nature Medicine, revealed 26 genetic regions that increase risk for fibromyalgia, with roughly half located near genes involved in nerve growth and pain perception and the strongest signal in a gene linked to Huntington’s disease. The research, led by Michael Wainberg and collaborators including Hanna Ollila, examined almost 55,000 diagnosed patients and found the disorder’s roots are primarily neurological, challenging the long-standing view of it as a psychological condition.

Commentators such as Jonathan Aebischer and Gerard Limerick highlighted the variability of symptoms and ongoing skepticism among some clinicians. While the identified variants cannot yet serve as diagnostic markers and the cohort did not represent all ancestries, the study offers a biological framework that may spur new treatment approaches. Patient advocate Kristal Kent hopes the work will improve clinician-patient dialogue and recognition of the illness.
