The findings, published in Nature Medicine, provide substantial evidence that fibromyalgia has a biological basis rooted primarily in the nervous system, challenging longstanding perceptions of the disorder as psychological in origin.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f241f77 elementor-widget elementor-widget-text-editor\" data-id=\"f241f77\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Researchers analysed the genomes of 2.5 million people, of whom nearly 55,000 had received a fibromyalgia diagnosis. The team, led by genetic epidemiologist Hanna Ollila of the University of Helsinki and geneticist Michael Wainberg of the University of Toronto, searched for genetic variants occurring more or less frequently in affected individuals compared with the general population.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bcdb794 elementor-widget elementor-widget-text-editor\" data-id=\"bcdb794\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Of the 26 identified risk variants, roughly half were located near genes involved in nerve cell growth and pain sensitivity regulation. The variant most strongly associated with fibromyalgia appeared in a gene linked to Huntington&#8217;s disease, a finding described by the researchers as unexpected. The authors clarify that the mutation responsible for Huntington&#8217;s disease is distinct from the variant identified in fibromyalgia, and that having one condition does not confer risk for the other. The functional role of this variant in fibromyalgia remains to be determined.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-05d7226 elementor-widget elementor-widget-text-editor\" data-id=\"05d7226\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Fibromyalgia affects an estimated four million adults in the United States and is characterised by widespread pain, fatigue, sleep disturbance, and cognitive difficulties. Diagnosis remains challenging due to symptom variability, the absence of validated biomarkers, and persistent scepticism within some areas of clinical practice.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a4a73a7 elementor-widget elementor-widget-text-editor\" data-id=\"a4a73a7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The authors acknowledge that the dataset did not fully represent all ancestries and that the identified variants are not currently suitable for diagnostic use.
