Gene profiling of patients with chronic fatigue syndrome/myalgic encephalomyelitis.
Kerr, Jonathan R·Current rheumatology reports·2008
Researchers used gene testing to look at which genes are turned on or off differently in people with ME/CFS compared to healthy people. They found 88 genes with different activity levels, mostly related to immune function and infection fighting. Importantly, they discovered that ME/CFS patients appear to fall into at least seven different subtypes based on their gene patterns, suggesting that ME/CFS may not be one single disease but rather several related conditions that might need different treatments.
