Background: The risk of colorectal cancer (CRC) and breast cancer (BC) is influenced by polymorphisms located in the genes encoding enzymes of the folate pathway. The aim of this study was to evaluate if A66G MTRR (rs1801394) polymorphism is involved in predisposition for colorectal and breast carcinogenesis in Romanian patients.
Materials And Methods: In the present case-control study, 300 individuals divide in four groups: sporadic CRC patients (n = 120), control CRC (n = 60), BC patients (n = 60) and control BC (n = 60), were genotyped by PCR-RFLP method.
Results: Frequency of genotype AA was 11.7% in CRC control and 5% respectively in BC control. For cancer groups the frequency of genotype AA was 9.2% in CRC and 0% in BC.
Conclusions: Study results do not demonstrate an association between A66G MTRR polymorphism and CRC or BC in Romanian patients.

To analyze whether the single-nucleotide polymorphisms (SNPs) in Matrix metalloproteinases 2, 3, and 9 (MMP2, MMP3, and MMP9), Tissue Inhibitor of Metalloproteinases 1 and 2 (TIMP1 and TIMP2), methionine synthase (MTR) and methionine synthase reductase (MTRR) influence delayed deciduous tooth eruption (DDTE). This cross-sectional study included 1060 biologic unrelated children (aged between 6 and 36 months) of both sexes, selected from 25 public schools in Nova Friburgo, Rio de Janeiro, Brazil. Oral examination was conducted and DDTE was defined by the absence of gingival eruption according to a chronology based on the Brazilian population.

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.

Accurate, rapid, and multiplex SNP analysis holds significant clinical value. However, the inevitable nucleic acid extraction, involving centrifugation, heating, and magnetic separation, is often time-consuming. In this study, direct blood PCR was combined with dual-labelled probe-mediated melting curves to identify SNPs corresponding to MTHFR (C677T, rs#1801133 and A1298C, rs#1801131) and MTRR (A66G, rs#1801394) in a single tube.

Background: Although many studies shown that the risk of congenital heart disease (CHD) was closely related to genetic and environmental factors, the exact mechanism was still unclear. This study was to assess the association of maternal folic acid supplementation (FAS), the 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) gene polymorphisms in offspring and their interaction effects with the risk of CHD and its subtypes.
Methods: A case-control study was conducted on 595 children with CHD and 605 healthy child controls.

Background: Methionine synthase reductase, which is encoded by the methionine synthase reductase () gene, plays a crucial role in the methylation reactions and the production of DNA and its epigenetic processes. There was a correlation between the (A66G) polymorphism and the likelihood of developing acute lymphoblastic leukemia (ALL). This study was carried out to investigate the correlation among pediatric ALL cases.
