A 55-year-old, previously healthy woman, presented with frequent headaches. She had no neurological disturbances, but had a positive family history; her father died from stroke. Magnetic resonance imaging showed brain infarction; therefore detailed diagnostic evaluation of thrombophilia markers and genetic testing were performed. The patient was found to be homozy- gous for the C677T mutation o...
Molecular beacons are oligonucleotide probes that become fluorescent upon hybridization. We designed molecular beacons to detect a point mutation in the methylenetetrahydrofolate reductase (MTHFR) gene, a mutation that has been related to an increased risk for cardiovascular disease and neural tube defects. The application of molecular beacons enables fast, semiautomated, accurate mutation dete...
Methods Genotypes were determined in an observational cohort of 183 JIA patients that had been systematically followed at 3 months intervals. The following SNPs were determined: methylenetetrahydrofolate reductase (MTHFR) 677C>T and 1298A>C, methionine synthase reductase (MTRR) 66A>G, thymidylate synthase (TS) 2R/3R and Reduced Folate Carrier (RFC) 80G>A. MTX efficacy and adverse effects were c...
Prior preparation of N(5),N(10)-methylenetetrahydrofolate from dl-tetrahydrofolate and [(14)C]formaldehyde resulted in an improved assay for thymidylate synthase. Although preparations from tobacco seedlings and cotton root tips (0.25 centimeter) were inconsistent with respect to enzyme activity, extracts from actively growing cell cultures of Chlamydomonas, Nicotiana hybrid callus, Pinus callu...
Recurrent pregnancy loss is usually defined as the loss of two or more consecutive pregnancies before 20 weeks of gestation, which occurs in approximately 5% of reproductive-aged women. It has been suggested that women with thrombophilia have an increased risk of pregnancy loss and other adverse pregnancy outcomes. Thrombophilia is an important predisposition to blood clot formation and is cons...
