C677T AND A1298C ALLELE POLYMORPHISM GENE OF METHYLENETETRAHYDRAFOLATEREDUCTASE IN PATIENTS WITH NONALCOHOLIC FATTY LIVER DISEASE AND TYPE 2 DIABETES

Abstract

The article presents the results of the study C677T and A1298C polymorphisms of MTHFR gene and their influence on plasma homocysteine levels in patients with nonalcoholic fatty liver disease (NAFLD). The study involved 100 patients with NAFLD and 40 apparently healthy individuals (control group). Determination of allelic polymorphism was performed by polymerase chain reaction with the detection results of hybridization by fluorescence in real-time. Determination of plasma homocysteine levels was performed by ELISA. As a result, studies have not found significant differences in the distribution of genotypes investigated C677T and A1298C MTHFR gene between patients with NAFLD and control group. We have detected statistically significant relationship between the level of homocysteine plasma C677T polymorphism of the MTHFR gene in patients with NAFLD and lack of connection with the A1298C polymorphism of the gene MTHFR.
