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
What is the function of the MTHFD1L gene?
It encodes a mitochondrial enzyme that contributes to folate metabolism and supports methylation and nucleotide synthesis.
How is MTHFD1L different from MTHFD1?
While both participate in one-carbon metabolism, MTHFD1L functions in the mitochondria, whereas MTHFD1 operates in the cytosol.
What can happen if you have a variant in MTHFD1L?
Variants may impair mitochondrial folate metabolism, potentially contributing to methylation issues or increased disease risk.
Is MTHFD1L linked to specific health conditions?
Yes, it has been associated with neural tube defects, cardiovascular disorders, and inefficient detoxification or DNA synthesis.
