How can you use “mthfr” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Additionally, the effect of the thermolabile MTHFR mutation (677 C→T) on plasma homocysteine levels in heterozygotes has been shown to depend upon the availability of folate, with higher levels seen in folate deficient individuals.

  • The most important of these are the aldose reductase gene ( ALR2 ) [ 17], the insertion/deletion (I/D) polymorphism of the angiotensin I - converting enzyme ( ACE ) gene [ 18, 19], C825T polymorphism of the gene encoding the beta-3 subunit of geterotrimeric G-proteins ( GNB3 ) [ 20, 21, 22], and C677T polymorphism of the methylenetetrahydrofolate reductase gene ( MTHFR ) [ 23].

  • Thus, we propose to study polymorphisms in genes involved in a number of systems and pathways related to stroke risk [ 5 ] : genes associated with coagulation factors and thrombophilia (Factor V, Prothrombin, Fibrinogen, Factor VII, Factor XIII, PAI-1, Thrombomodulin [TM], and MTHFR), as well as polymorphisms in genes that are involved in vascular reactivity (ACE), platelet activation/function (GpIIb/IIIa, GpIb IX-V, and GpIa/IIa), endothelial cell function (MTHFR, TM, VCAM-1, E-Selectin, L-Selectin, P-Selectin, and ICAM-1), inflammation (TNFα), lipid metabolism (Apo A1 and Apo E), and cell adhesion (VCAM-1, E-Selectin, L-Selectin, P-Selectin, and ICAM-1).

  • However, despite association of the factor V G1691A (factor V Leiden) and prothrombin (factor II) G20210A mutations with venous thromboembolism and myocardial infarction [ 10 11 ] , neither mutation is strongly associated with risk of stroke [ 12 13 14 15 16 17 18 ] . Although a study of British adults found elevated levels of serum homocysteine to be associated with an increased risk of stroke [ 19 ] , a case-control study of a common polymorphism (methylenetetrahydrofolate reductase [MTHFR] T677C) that results in increased serum homocysteine concentrations found no difference between patients with stroke and controls in either genotype or allele frequency [ 20 ] . Because antiplatelet agents with different mechanisms of action can bring about significant reductions in stroke risk, several platelet receptor genes have been tested as candidate stroke susceptibility genes [ 21 22 ] . To date, however, no compelling evidence for an association between any platelet receptor gene polymorphism and risk of stroke has been found.

  • It is possible that increased folate requirements due to chronic hemolysis in sickle cell disease would lead to a relative deficiency state, which, in the presence of MTHFR mutation, would result in higher homocysteine levels as an additional risk factor for vasculopathy.
