MTHFR C677T & A1298C Genetic Mutation Test – DNA Analysis for Methylation & Health Insights

The MTHFR C677T & A1298C Genetic Mutation Test from Lab Tests Dubai is a precision DNA screening that identifies two of the most clinically significant variants in the MTHFR (methylenetetrahydrofolate reductase) gene a critical enzyme involved in folate metabolism, methylation, and homocysteine regulation.

These common genetic variations can reduce MTHFR enzyme activity by up to:

• ✅ 70% in homozygous C677T (TT genotype)
• ✅ 40–60% in compound heterozygotes (C677T + A1298C)

When impaired, this leads to:

• Poor conversion of folic acid to active methylfolate (5-MTHF)
• Elevated homocysteine levels (linked to heart disease, stroke)
• Reduced detoxification, neurotransmitter production, and DNA repair
• Increased risk of infertility, recurrent miscarriage, and neural tube defects

This test is essential for:

• Individuals with high homocysteine despite normal folate/B12
• Women experiencing recurrent pregnancy loss or infertility
• Patients with depression, anxiety, or brain fog
• People struggling with chronic fatigue or cardiovascular risks
• Those optimizing health through functional or integrative medicine

Using CLIA-certified PCR or NGS technology, this non-invasive cheek swab or saliva test delivers accurate results within 5–10 business days so you can start supporting your biochemistry with the right form of folate.

Available with home sample collection, Lab Tests Dubai ensures privacy, precision, and proactive care empowering you to thrive at the genetic level.

Why You Need This Test

If you’re taking folic acid but still feel tired, anxious, or unwell, this test could reveal why your body may not be able to activate synthetic folic acid due to an MTHFR mutation.

You need the MTHFR C677T & A1298C Test if:

• You’ve had recurrent miscarriages or implantation failure
• You suffer from chronic fatigue, depression, or brain fog
• You’re planning pregnancy or undergoing IVF
• You take folic acid supplements but see no benefit
• You have a family history of stroke, blood clots, or early heart disease

This test helps:

• Identify impaired folate metabolism
• Guide use of active folate (5-MTHF) instead of folic acid
• Lower homocysteine naturally with targeted B vitamins
• Support healthy conception and fetal development
• Improve mood, energy, and detox pathways

Symptoms That Indicate This Test

Consider the MTHFR Test if you experience:

• For Methylation & Mental Health:

• Chronic fatigue or low stamina

• Anxiety, depression, or mood swings

• Brain fog, poor memory, or difficulty concentrating

• Insomnia or sleep disturbances

• For Fertility & Pregnancy:

• Recurrent miscarriages (especially 1st trimester)

• Infertility or failed IVF cycles

• History of preeclampsia or placental issues

• Neural tube defects in previous pregnancies

• For Cardiovascular Risk:

• High homocysteine levels

• Family history of stroke or clotting disorders

• Unexplained blood clots (DVT, PE)

These signs may point to impaired methylation and this test helps start the right treatment.

Natural Production: How MTHFR Supports Your Body

The MTHFR enzyme converts:

• Dietary folate and synthetic folic acid → L-methylfolate (5-MTHF)

This active form is essential for:

• ✅ DNA synthesis and repair
• ✅ Neurotransmitter production (serotonin, dopamine, melatonin)
• ✅ Detoxification and hormone balance
• ✅ Lowering homocysteine (high levels damage blood vessels)

What Happens If Untreated? Risks of Ignoring MTHFR Mutations

Ignoring MTHFR dysfunction can lead to:

⚠️ Elevated Homocysteine – increases risk of heart attack, stroke, dementia

• Pregnancy Complications – miscarriage, preterm birth, birth defects
• Neuropsychiatric Issues – depression, anxiety, bipolar-like symptoms
• Chronic Fatigue & Poor Detoxification
• Misdiagnosis as psychiatric or autoimmune condition

The good news? This is highly manageable with:

• Active folate (L-5-MTHF) – bypasses the genetic block
• Vitamin B12 (methylcobalamin) – supports methylation cycle
• B6 (P-5-P) and Betaine (TMG) – help clear homocysteine
• Lifestyle support (stress reduction, toxin avoidance)

How to Prepare for the Test

To ensure accurate results:

• No fasting required
• Avoid eating, drinking (except water), smoking, or chewing gum 30 minutes before sample collection
• Use the sterile cheek swab or saliva kit provided
• Follow the step-by-step instructions for sealing and mailing
