Hypothesis

Can genetic polymorphisms in MTHFR and DNMT genes influence global DNA methylation profiles?

Conclusion

Polymorphisms in the MTHFR and DNMT genes may influence the global DNA methylation profile in various health contexts.

Supporting Evidence

  • Polymorphisms in the MTHFR and DNMT genes were associated with global DNA methylation levels.
  • Different studies showed varying results based on the context of the genetic variants.
  • Some studies indicated that the same polymorphism could be linked to both higher and lower methylation levels.

Takeaway

Some genes can change how our DNA is marked, which can affect our health. This study looks at how certain gene changes might change these marks.

Methodology

A narrative review of studies published in the last 15 years.

Potential Biases

Potential biases due to the variability in sample populations and methodologies used across studies.

Limitations

The review is limited by the variability in study designs and the context-dependent nature of the associations.
