A Comprehensive Review of the Genetic and Epigenetic Contributions to the Development of Fibromyalgia

This narrative review summarizes the current knowledge of the genetic and epigenetic contributions to the development of fibromyalgia (FM). Although there is no single gene that results in the development of FM, this study reveals that certain polymorphisms in genes involved in the catecholaminergic pathway, the serotonergic pathway, pain processing, oxidative stress, and inflammation may influence susceptibility to FM and the severity of its symptoms. Furthermore, epigenetic changes at the DNA level may lead to the development of FM. Likewise, microRNAs may impact the expression of certain proteins that lead to the worsening of FM-associated symptoms.

Automated summary

This narrative review provides an overview of the current understanding of the genetic and epigenetic contributions to the development of fibromyalgia (FM). While no single gene has been identified as the cause of FM, this study suggests that certain genetic polymorphisms involved in various pathways may influence susceptibility to FM and the severity of its symptoms. Additionally, epigenetic changes at the DNA level and the impact of microRNAs on protein expression are also implicated in the development and worsening of FM-associated symptoms.
