Understanding MTHFR & MTRR Genes


1.  Role and Importance of MTHFR & MTRR Genes

Our bodies are wonderlands of complex biochemical processes, and MTHFR & MTRR genes play crucial roles in these operations. Both these genes create enzymes vital for our well-being. MTHFR (methylenetetrahydrofolate reductase) catalyses the conversion of folate into a form that the body can utilize. MTRR (methionine synthase reductase) helps maintain a pivotal enzyme, methionine synthase, crucial for the synthesis of methionine, an essential amino acid. Both these genes effectively influence our health at the cellular level, impacting everything from heart health to mental well-being.

2.  The Process of Methylation and Its Importance

Now, let’s delve into the methylation process. It’s a simple transfer of four atoms—one carbon atom and three hydrogen atoms—from one substance to another. Sounds simple, right? However, it’s this simple biochemical process that plays a crucial role in maintaining and regulating a wide range of bodily functions—DNA repair, toxin detoxification, stress response, and energy production, to name a few. It’s like the oil that keeps our biological engine running smoothly.


3.  Detoxification and These Genes

Lastly, the connection between detoxification and these genes lies within methylation’s broad spectrum of functions. A well-functioning methylation process assists in eliminating toxins and heavy metals from our body, effectively acting as our body’s natural detoxification system. However, if you have certain variations in your MTHFR & MTRR genes, the methylation process can be less efficient, potentially leading to a buildup of toxins and the onset of health issues. As a result, understanding these genes can offer us a blueprint for personalised healthcare, directing our lifestyle choices towards optimal health and well-being.

Effects of Genetic Variation

1.  Deciphering Variants of MTHFR & MTRR Genes

In the world of genetics, a “variant” refers to any change in a DNA sequence. For the MTHFR gene, two common variants are the C677T and A1298C. These variants can impact the enzyme’s effectiveness, altering the methylation process, and hence, our health. Similarly, the MTRR gene also has variants, most notably A66G. Variants in this gene can lead to elevated homocysteine levels, a risk factor for several health conditions.


2.  How MTHFR & MTRR Gene Variants Affect Health

Genetic variations can influence our health in ways we’re only just beginning to understand. MTHFR gene variants can lead to reduced enzyme activity and impact homocysteine metabolism. This can increase the risk of conditions like:

  • cardiovascular disease,
  • birth defects,
  • certain cancers, and
  • mental health disorders.

On the other hand, MTRR gene variants, by affecting methionine synthesis, can lead to:

  • elevated homocysteine levels, potentially increasing the risk of neurological disorders,
  • cardiovascular diseases, and other health issues.

These impacts highlight the importance of understanding your genetic variants, paving the way for personalized healthcare strategies.


3.  The Influence of Genetic Variants on Folate Metabolism

Folate metabolism is a key process in our bodies, playing an essential role in cell growth and development. Variations in the MTHFR gene can lead to a reduction in the body’s ability to convert folate (or folic acid) from the diet into its usable form, methylfolate. This can result in a condition known as ‘folate deficiency’, which may lead to:

  • anemia,
  • changes in skin,
  • hair, or fingernail color, and
  • an increased risk of birth defects in pregnant women.

By understanding our genetic predispositions, we can tailor our nutritional intake and lifestyle habits to ensure optimal health and well-being.

Studies have attempted to link mutations in MTHFR to over 600 different medical conditions Source

The MTHFR gene has several genotypes, including the 677 CC and 677 TT genotypes. Here are some key differences between these two genotypes:

  • (The 677CC genotype is the wild-type form of the MTHFR gene, while the 677TT genotype is a homozygous variant of the MTHFR gene

  • The 677CC genotype has normal enzyme activity, while the 677TT genotype has less than 30% of the normal enzyme activity
