conclusions our findings suggest that there is an association between the mthfr c677t polymorphism and susceptibility for the development of ra. results our results showed significant differences between the groups with respect to mthfr c677t genotype (p = 0.015) and allele frequencies (0.004). statistical analysis showed that there is no relation between gender, age, and ra risk. however, we fo...

BACKGROUND Methylenetetrahydrofolate reductase (MTHFR), a critical enzyme in folate metabolism is involved in DNA synthesis, DNA repair and DNA methylation. The functional polymorphism of MTHFR gene, C677T has been shown to impact various diseases and implicated as a risk factor for the development of various neurodegenerative disorders including glaucoma. METHODS We investigated MTHFR C677T ...

background recurrent pregnancy loss (rpl) is a serious problem for pregnancy. there is evidence that vascular complications play a principal role in rpl. methylenetetrahydrofolate reductase (mthfr) is a key enzyme in folate metabolism. polymorphisms (c677t, a1298c) of mthfr gene are associated with decreased mthfr activity. objectives the aim of this study was to determine the association betwe...

Objective: Down Syndrome (DS) is defined as chromosome 21 trisomy and associated with cardiovascular system diseases. We aimed to study inherited thrombophilia genes (MTHFR A1298C, MTHFR C677T, Factor II G20210A, V Leiden G1691A, Cambridge G1091C, XIII, APOB, ITGB3, FVHR2, FGB, PAI-1 ACE) in patients DS. Materials Methods: A total of 53 DS (32 male female) were included the study. Demographical...

ناباروری تحت عنوان عدم باروری پس از طی دوره زمانی معمولا یک سال آمیزش بدون جلوگیری تعریف می شود. تقریبا 15 درصد از زوجها نابارورند و در این میان، فاکتور مرد حدود 50 درصد از موارد را شامل می شود. ناباروری مردان، یک سندرم چند عاملی است که به عوامل ژنتیکی و محیطی گوناگونی بستگی دارد. در 25 درصد موارد ناباروری مردان، علت ناباروری نامشخص است و می تواند مادرزادی یا اکتسابی باشد که اینها تحت عنوان موا...

Major congenital malformations occur in about 3% of newborn. Several studies have suggested that homozygosity for the C677T methylenetetrahydrofolate reductase (MTHFR) variant is a potential risk factor for neural tube defects (NTDs). It has been hypothesized that the maternal folic acid supplementation prevents NTDs by partially correcting reduced MTHFR activity associated with the variant for...

The methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism was studied in 174 German patients with cervical artery dissection (CAD). The results were compared with published data on 927 healthy German controls. In the series of patients, the frequency of T alleles and of TT carriers was slightly higher (13.8%) than among the healthy controls (10.6%). In patients with multiple dissectio...

Polymorphisms in genes encoding enzymes of folate metabolism are a focus of breast cancer risk studies due of the role of these enzymes in DNA methylation, synthesis, and repair. MTHFR, encoding for 5,10-methylenetetrahydrofolate reductase, is one of the most studied genes in this regard, but findings are controversial, and the majority of studies have analyzed polymorphisms individually. In th...

BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease, which includes a spectrum of hepatic pathology such as simple steatosis, steatohepatitis, fibrosis and cirrhosis. The increased serum levels of homocysteine (Hcy) may be associated with hepatic fat accumulation. Genetic mutations in the folate route may only mildly impair Hcy metabolism. The aim of this study was t...
