The association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism, circulating levels of homocysteine (Hcy), and the severity of coronary lesion in patients with acute coronary syndrome (ACS) remains unknown.Consecutive ACS patients were included. MTHFR C677T polymorphisms were determined via amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Gensini scores were used to evaluate the severity of coronary lesions.Three hundred ten ACS patients were included, and grouped according to the MTHFR C677T polymorphism variant: CC (n = 78, 25.2%), CT (n = 137, 44.2%), and TT (n = 95, 30.6%) groups. No significant differences were detected with respect to baseline characteristics. Patients in TT group had significantly higher Hcy, and significantly lower folic acid (FA) levels as compared with those in the other 2 groups (P < .05 for both). More importantly, patients with TT had more severe coronary lesions as compared with those from the other 2 groups, as evidenced by higher Gensini scores (P < .05 for both); however, no significant differences were observed with respect to the numbers of affected coronary arteries, or the number, length, and diameter of stents implanted in each group (P > .05 for all). On multivariate logistic regression analysis, presence of a T allele in MTHFR C677T was found to be independently associated with higher circulating Hcy (odds ratio [OR] = 1.06, 95% confidence interval [CI]: 1.01-1.12, P = .024), and higher Gensini scores (OR: 1.01, 95% CI: 1.00-1.02, P = .046).MTHFR C677T TT polymorphism was associated with higher Hcy levels and more severe coronary lesions in patients with ACS.

Methylenetetrahydrofolate reductase (MTHFR) gene is involved in homocysteine and folic acid metabolism. Tumour suppressor protein TP53 gene maintains cellular and genetic integrity. To date, no studies associated the MTHFR C677T rs1801133 and TP53 Pro72Arg rs1042522 with CRP levels and methotrexate (a folic acid antagonist) treatment outcomes in psoriatic arthritis (PsA) patients.

Background And Objectives: Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme that regulates folate and homocysteine metabolism. Genetic variation in has been implicated in cerebrovascular disease risk, although research in diverse populations is lacking. We thus aimed to investigate the effect of genetically predicted MTHFR activity on risk of ischemic stroke (IS) and its main subtypes using a multiancestry Mendelian randomization (MR) approach.

Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) polymorphisms are known risk factors for vascular diseases due to the impact on folate metabolism dysfunction and homocysteine (Hcy) accumulation. This study aimed to investigate the association between folate metabolism risk and hemorrhagic risk in moyamoya disease (MMD). In this prospective study, we enrolled 350 MMD patients with complete genotype data for MTHFR and MTRR.

The ( C677T gene polymorphism is associated with neurological disorders and schizophrenia. Patients diagnosed with schizophrenia and schizoaffective disorder and controls ( 134) had data collected for risk factors, molecular and neuro-sensory variables, symptoms, and functional outcomes. Promising gene variant-related predictive biomarkers were identified for diagnosis by Receiver Operating Characteristics and for illness duration by linear regression.
