[Mutations in the methylene-tetrahydrofolate reductase gene and Down syndrome].
Down syndrome (DS) is a complex genetic and metabolic disorder attributed to the presence of three copies of chromosome 21. The extra chromosome derives from the mother in 93% of cases and is due to abnormal chromosome segregation during meiosis (nondisjunction). Except for advanced age at conception, maternal risk factors for meiotic nondisjunction are not well established. A recent preliminar...
متن کاملEndocrine sequelae and metabolic syndrome in adult long-term survivors of childhood acute myeloid leukemia.
This study focuses on the effect of chemotherapy on endocrinopathies and the metabolic syndrome in adult survivors of childhood acute myeloid leukemia (AML). Endocrine function and metabolic syndrome were evaluated in 12 AML survivors, treated with chemotherapy, and in 9 survivors of myeloid leukemias treated with stem cell transplantation (SCT), after a median follow-up time of 20 years (range...
متن کاملAssociation between methylene tetrahydrofolate reductase and glutathione S-transferase M1 gene polymorphisms and chronic myeloid leukemia in a Brazilian population.
Chronic myeloid leukemia is a hematopoietic stem cell disorder that causes uncontrolled proliferation of white blood cells. Although the clinical and biological aspects are well documented, little is known about individual susceptibility to this disease. We conducted a case-control study analyzing the prevalence of the polymorphisms MTHFR C677T, MTHFR A1298C, del{GSTM1}, del{GSTT1}, and h...
متن کاملSex differences in risk of lung cancer associated with methylene-tetrahydrofolate reductase polymorphisms.
Methylenetetrahydrofolate reductase (MTHFR) catalyzes the metabolism of folate and nucleotides needed for DNA synthesis and repair. Variations in MTHFR functions likely play roles in the etiology of lung cancer. The MTHFR gene has three nonsynonymous single nucleotide polymorphisms (i.e., C677T, A1298C, and G1793A) that have a minor allele frequency of >5%. We investigated the associations betw...
متن کاملPrevalence of methylene tetrahydrofolate reductase polymorphism in South Indian population
Prevalence of methylene tetrahydrofolate reductase (MTHFR) gene mutations in South Indian population was investigated from a total of 608 samples, 420 adults and 188 newborns. Detection of mutation was carried out focussing on the two most common mutations of the MTHFR gene (C677T and A1298C) using PCRbased RFLP method. T-allele frequency was almost similar between the newborns and adults (0.09...
