The MTHFS gene encodes methenyltetrahydrofolate synthetase, an enzyme involved in folate metabolism. It plays a crucial role in maintaining the pool of active folate derivatives used for methylation, DNA synthesis, and neurotransmitter production. MTHFS regulates the conversion of various folate forms and helps maintain the balance of one-carbon units essential for cellular function. Variants in this gene may disrupt folate recycling, potentially affecting methylation pathways and contributing to issues such as impaired detoxification, fatigue, or mood imbalance.
MTHFS encodes an enzyme that helps regulate folate metabolism and supports methylation and nucleotide synthesis.
It ensures proper recycling and balance of folate derivatives that are needed for effective methylation and DNA replication.
They may lead to inefficient folate use, contributing to elevated homocysteine, reduced detox capacity, or neurological symptoms.
They could be associated with fatigue, poor concentration, mood disorders, or sensitivity to folic acid supplements.
