MTHFD1L
The MTHFD1L gene encodes a mitochondrial enzyme involved in the folate cycle and one-carbon metabolism, specifically in the conversion of formate to 10-formyl-THF. This process supports purine synthesis and methylation reactions, which are essential for DNA and RNA production and cellular repair. Genetic variations in MTHFD1L can affect mitochondrial folate metabolism and have been associated with an increased risk of neural tube defects, cardiovascular issues, and impaired methylation. It plays a complementary role to the cytosolic MTHFD1 gene but operates within the mitochondria.
Description
It encodes a mitochondrial enzyme that contributes to folate metabolism and supports methylation and nucleotide synthesis.
While both participate in one-carbon metabolism, MTHFD1L functions in the mitochondria, whereas MTHFD1 operates in the cytosol.
Variants may impair mitochondrial folate metabolism, potentially contributing to methylation issues or increased disease risk.
Yes, it has been associated with neural tube defects, cardiovascular disorders, and inefficient detoxification or DNA synthesis.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
