Patient surpassed TIA with right-sided hemiparesis in the past, with diagnosis of homozygous mutation in MTHFR (Methylene tetrahydrofolate reductase). The MTHFR gene produces an enzyme that helps regulate homocysteine levels in the body. Disorders in homocystein metabolism are associated with increased risk of vein thrombosis and are connected with vascular wall damage. The exact connection and mechanisms are still not well known.
