DNA Methylation as a Common Factor in Complex Chronic Diseases

Updated

Abstract

Epigenetic DNA methylation may offer insights into four complex chronic conditions that are often mismanaged.

  • Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), long COVID (LC), fibromyalgia (FM), and hypermobile Ehlers-Danlos syndrome (hEDS) exhibit overlapping symptoms.
  • There is potential for shared underlying biological mechanisms among these conditions.
  • DNA methylation serves as a useful framework for studying these interconnected disorders.
  • Current studies on DNA methylation in ME/CFS, LC, and FM suggest that an integrated approach may enhance understanding of their mechanisms.
  • This approach could assist in better diagnostic stratification and potentially improve patient outcomes.
