Published in Nature Medicine, a multi-ancestry genome-wide association study meta-analysis encompassing 2,563,755 individuals has identified 26 risk loci for fibromyalgia—including the HTT gene—revealing genetic correlations with chronic pain, psychiatric conditions, and somatic disorders.
Unlocking the Complex Genomic Architecture of Fibromyalgia
The publication of a genetic study in Nature Medicine utilized genomic data across 2,563,755 multi-ancestry individuals to isolate 26 genomic risk loci tied to the condition. This genome-wide association study meta-analysis identifies a biological architecture for fibromyalgia.
Among the discoveries is the identification of the HTT gene locus among the risk factors. Furthermore, the analysis established genetic correlations between fibromyalgia and other chronic pain syndromes, various psychiatric disorders, and somatic comorbidities.
In Plain English: The Clinical Takeaway
- What was done: Researchers scanned the DNA of over 2.5 million people of diverse ancestries to find genetic markers shared more often by individuals with fibromyalgia.
- What was found: The team uncovered 26 specific genetic regions (loci)—including the HTT gene—that elevate a person’s susceptibility to the disorder.
