Factors which affects MTHFR

Author: Aravindan

Hypermethylation of the MTHFR promoter—an epigenetic mechanism that silences gene expression—is primarily driven by chronic systemic inflammation, oxidative stress, and certain disease states like Type 2 Diabetes. 

Key Drivers of MTHFR Hypermethylation

Chronic Oxidative Stress & Inflammation: Research, such as studies published in the SpringerLink Article on MTHFR Methylation, shows a strong correlation between elevated inflammatory markers (like alpha-1 acid glycoprotein) and MTHFR promoter hypermethylation. 

Diabetic Complications: Hypermethylated profiles of MTHFR are significantly more frequent in individuals suffering from chronic conditions like diabetic retinopathy (DR) or diabetic nephropathy (DN), alongside dyslipidemia (high cholesterol and LDL). 

Folate Metabolism Disturbances: Epigenetic silencing of this promoter directly impairs one-carbon metabolism and folate processing, creating a feedback loop where downstream methylation capacity is altered.
