Summary
Elevated plasma homocysteine (Hcy) is a risk factor for deep-vein thrombosis (DVT). The interaction between low folate levels and MTHFR genotype significantly increases DVT risk.
Area of Science:
- Medical Science
- Genetics
- Hematology
Context:
- Deep-vein thrombosis (DVT) is a significant vascular condition.
- Hyperhomocysteinemia, a condition of elevated homocysteine levels, is implicated in thrombotic events.
- The role of methylenetetrahydrofolate reductase (MTHFR) gene polymorphism and folate status in DVT pathogenesis requires further elucidation.
Purpose:
- To investigate the association between plasma homocysteine (Hcy) levels and deep-vein thrombosis (DVT).
- To analyze the interplay of Hcy, folate, and MTHFR gene polymorphism in DVT patients.
- To determine if MTHFR C677T genotype and folate levels are independent risk factors for DVT.
Summary:
- Plasma Hcy levels were significantly higher in DVT patients compared to controls.
- No significant difference in MTHFR C677T genotype frequencies or serum folate/vitamin B12 levels was observed between groups.
- Hyperhomocysteinemia was identified as an independent risk factor for DVT, with a notable interaction between low folate and the MTHFR TT genotype increasing DVT risk.
Impact:
- Findings suggest hyperhomocysteinemia is a key risk factor for DVT in the Han population.
- Serum folate levels and MTHFR C677T genotype alone are not significant risk factors.
- The interaction between folate status and MTHFR genotype significantly contributes to DVT risk, highlighting potential therapeutic targets.
