Parkinson's disease (PD) is a common neurodegenerative syndrome directly related to age development. This pathologic condition presents in many types of forms. Some efforts applied to understand PD development include regulation of epigenetic mechanisms, which usually include minor molecular modifications of DNA and histones, which are essential to regulate genetic activity. We have highlighted the problems associated with the development of genetic and epigenetic processes and reviewed several studies. None of these led to more vital conclusions about the autonomous roles of epigenetic pathways. Data from the current standpoint suggested that the SNCA, one of the hallmark genes implicated in PD, is more prevalent than pathways that directly require DNA methylation due to complicated DNA hydroxyl-methylation, global hyper-acetylation and histone deacetylase (HDAC). Without current epigenetic clinical goals to delay PD progression, we hypothesize how PD neurons, with the potential therapeutic objectives, can affect local and global epigenetics via inflammation, oxidative stress, autophagy and DNA repair mechanisms.

Graphical Abstract

Genetic and epigenetic collaboration in Parkinson’s disease


  • Parkinson's disease (PD) is a common neurodegenerative syndrome.
  • Reduced activity of dopamine (DA) in Substantia Nigra is linked to PD.
  • Epigenetics and genetics are highly interconnected in PD.
  • 10–15% prevalence of Parkinson's disease has a family-oriented basis.
  • SNCA has a role in the pathogenesis of Parkinson's disease.
