Epigenetics account for two-thirds of Alzheimer’s disease

The genetics percentage from a 2017 summary of Alzheimer’s disease research caught my eye:

“Although numerous single nucleotide polymorphisms (SNPs) have now been robustly associated with AD via genome-wide association studies and subsequent meta-analyses, collectively these common SNPs are believed to only account for 33% of attributable risk and the mechanism behind their action remains largely unknown.”

This citation aligned with other studies’ findings per Using twins to estimate the extent of epigenetic effects that on cellular levels, our experiences account for two-thirds of who we are.


The promise of this category of epigenetics research?

“One of the most exciting aspects of identifying disease-associated epigenomic dysfunction is that these mechanisms are potentially reversible.”

Let’s make research on reversing epigenetic changes a priority for funding, and get studies underway here in 2017!
