DNA testing applied to fibromyalgia syndrome analysis and management

FMS has been long considered as a psychogenic or psychosomatic disease. Most patients are suffering this stigma because they show many symptoms which are too many and too diverse to be considered as a single organic disease. For that reason, it is more appropriate to consider fibromyalgia as a syndrome with a vast heterogeneity in causes as well as in severity of symptoms and clinical evolution. It is a health problem which is very frequent in Spain having a prevalence of 2.4% of the population older than 20 years and being more frequent in women than in men, in a ratio of 21:1. Despite the high prevalence, its etiology remains unknown and no effective treatments exist [4].
