MTHFR C677T

(ii) Results for rs1042522 genotyping: Indian patients had a higher frequency of the variant Arg-allele versus healthy Indian controls (42% versus 29%; OR=1.75, 95% CI=1.07-2.86, p=0.0275). In conclusion, patients with the MTHFR rs1801133 variant T-allele have elevated CRP levels, which can be ameliorated with methotrexate.

The risk of developing oral mucositis in children with mature B-cell lymphoma is associated with plasma MTX concentration. Polymorphism of MTHFR C677T gene is not related to plasma MTX concentration in children with mature B-cell lymphoma, but is related to grade III to IV hematological toxicity.

Our findings indicate that these genetic polymorphisms are not only pivotal in understanding thrombophilia but also have broader implications for cardiovascular disease and cancer. This study highlights the need for further research into the combined effects of genetic and epigenetic factors on health, which could lead to improved screening and personalized preventive healthcare strategies.

No obvious association was observed between these MTHFR polymorphisms and cardiovascular risk in T2DM. Our study suggests that the genetic variations of MTHFR C677T and A1298C are significantly associated with T2DM susceptibility in the population of the Dali area of Yunnan Province, China.

Single difference of MTHFR C677T, MTHFR A1298C and MTRR A66G gene polymorphisms may have little effect on the disease progression in patients with chronic HBV infection. MTHFR 677CT + TT, MTRR 66AG + GG and MTHFR 1298AA genotype combined with HBV gene BCP region 1762/1764 mutation may be closely related to the occurrence and development of hepatitis B liver cancer.

MTHFR gene polymorphisms are associated with homocysteine (Hcy) levels, which affects vascular endothelial function and may be related to the development of vascular ED (VED). Folic acid supplementation improves International Index for Erectile Function (IIEF) questionnaire scores in ED patients in whom phosphodiesterase 5 inhibitor (PDE5i) alone is ineffective.

There was no overall association between MTHFR gene polymorphisms (C677T and A1298C) and NHL risk, but stratified analyses revealed significant associations in specific subgroups. While meta-analyses inherently build upon existing studies, our work distinguishes itself by incorporating recent data, applying rigorous analytical techniques, and providing more evidence of the MTHFR C677T polymorphism as an eQTL.

The distributions of MTHFR and MRRR genetic polymorphisms in the population with HBV infections in Zigong, Sichuan Province did not differ in age and sex. The MTHFR and MRRR genetic polymorphisms were comparable between the CHB, LC, and PLC groups.

According to the findings of this study, the mutant allele of the Methylene Tetra Hydro Folate Reductase C677T was detected and demonstrated varying degrees of significance. It was concluded that the MTHFR C677T gene mutation was associated with acute lymphoblastic leukemia in Sudanese patients.

These findings indicate a potential protective effect against digestive system cancer associated with the T allele of MTHFR C677T. Moreover, we observed that the presence of different combinations of MTHFR polymorphisms may contribute to varying susceptibilities to digestive system cancer.
