UK Researchers Identify Genetic Links To Chronic Fatigue Syndrome In Groundbreaking Study

Researchers at the University of Edinburgh have identified DNA differences in individuals with chronic fatigue syndrome (CFS), challenging the belief that the condition is psychological. The study highlights eight genetic code areas distinct in people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) compared to healthy individuals. This discovery offers strong evidence that genetics play a role in developing this disease, according to the researchers.

ME/CFS is characterised by increased fatigue, pain, and cognitive difficulties following minor physical or mental exertion. Despite affecting approximately 67 million people globally, its causes remain largely unknown, and there is no diagnostic test or cure available. The DecodeME study examined DNA from 15,579 individuals reporting chronic fatigue and 259,909 without it, all of European descent.

The study found gene variants more prevalent in those with ME/CFS linked to immune and nervous systems. At least two gene regions are associated with infection response, aligning with reports that symptoms often begin after an illness. Another gene region has been previously identified in individuals experiencing chronic pain, a common symptom of ME/CFS.

Andy Devereux-Cooke, a researcher involved in the study, stated that these findings "align with decades of patients reporting on their experiences" and could be transformative for ME/CFS research. He noted that while immediate development of tests or cures is unlikely, the results will enhance understanding of the condition.

Some scientists not involved in the research expressed concerns about using self-reported data rather than medically diagnosed cases of CFS. They suggested this might weaken conclusions and recommended larger studies to confirm these findings. Dr. Jackie Cliff from Brunel University emphasised that translating these findings into treatments will require significant investment from both academia and industry.

The research underscores the need for further exploration into genetic factors contributing to ME/CFS. Understanding these genetic links could eventually lead to better diagnostic tools and treatments for those affected by this debilitating condition.
