Both MTHFR and COMT genes are involved in the methylation pathway and testing their function is an important component of your anti-aging strategy. Think of billions of on/off switches that control most of your body’s functions such as:

• Brain chemistry important for mood, anxiety and stress
• Immune function
• Controlling inflammation
• Energy production
• Detoxification of chemicals and toxins
• Cardiovascular health

When methylation is working, it helps you feel full of energy, in a good mood, and just generally well! When it is not working, you can feel tired, depressed, irritable, run-down, susceptible to infections, foggy-brained, and just plain "toxic." This genetic methylation profile looks for gene mutations (also called SNP's) of the following two enzymes:

• MTHFR - (5,10-methylenetetrahydrofolate reductase)
• Research has shown that some people may be at risk of methylation insufficiency due to reduced MTHFR enzyme function.¹
• Two common mutations in the MTHFR gene (C677T and A1298C) may contribute to increased levels of homocysteine, a known risk factor for heart disease, atherosclerosis² and venous thrombosis.³
• Those with a genetic mutation in MTHFR will have varying levels of difficulty creating the active form of folic acid which is the important form the body needs to function properly.
• Maintaining levels of activated folate may also aid in preventing depression.^4-6
• Those with a genetic mutation in MTHFR should consider taking activated folate vs. regular folic acid.
• The best genotype to have in the C677T position is CC since it contains no mutations. The worst genotype to have in this position is TT since it contains two copies of the mutation.
• The best genotype to have in the A1298C position is AA since it contains no mutations. The worst genotype to have is CC since it contains two copies of the mutation.

• COMT - (Catechol-O-methyltransferase)
• A common mutation in COMT, the conversion of the amino acid valine to methionine at positon 158 causes a dramatic reduction in its ability to break down neurotransmitters.^7-9
• Since COMT is central to dopamine metabolism, mutations are associated with lowered stress resiliency, increased sensitivity to pain^10,11 and the propensity to worry.
• COMT also plays a role in estrogen metabolism and may lower the cancer-causing potential of metabolites^.12
• The wildtype genotype is GG (Val/Val) since it contains no mutations. The homozygous mutated genotype is AA (Met/Met) since it contains two copies of the mutation.

Genetic testing allows you to see inside your own DNA in order to draw a personalized map regarding imbalances that might impact your health. Genetic mutations are simply pieces of a much larger puzzle that allow you to see "potential" risks and take action in a preventative fashion. Although genetic mutations do not change over time, understanding them allows you to choose diet, supplementation and lifestyle changes to support good health.

Instructions

The following documents provide a full set of instructions for completing the test:

Note

Results take 2-3 weeks from when specimen is received. This test is not available in Pennsylvania. The results for this test can only be received via mail, e-mail, or fax. Since genetic mutations do not change over time, each person needs to be tested only once in their lifetime.
