Associação da mutação G1691A (fator V de Leiden) no gene do fator V da coagulação, da mutação G20210A no gene da protrombina e das mutações C677T e G1793A no gene da metilenotetrahidrofolato redutase com a doença arterial coronariana

Abstract

The coronary artery disease is a major cause of morbidity and mortality of people, especially those who inhabit the developed regions. The considered risk factors for the development of this disease are quite known and analyzed, being observed an increasingly regard to the risks of genetic and a verification of human polymorphic systems’ association to the propensity to develop a particular disease. From these studies it was possible to imagine the occurrence of so-called genetic markers, where the authors hold an attempt to view the possibilities of these markers be correlated to the disease examined. The purpose of this work was to establish and verify the validity of a molecular methodology capable of characterizing the mutation in G1691A in the gene of the clotting factor V, the mutation in the gene G20210A prothrombin and of the mutations in the gene C677T and G1793A of methylene-tetrahydrofolate reductase. With this option, check and correlate the frequency of these mutations in individuals with coronary artery disease, in non individuals with coronary artery disease and in blood donors in a share of the Paulista population. Hence, three groups of study were established, consisting in residents of the region of Sao Jose do Rio Preto, São Paulo, two of them classified by coronary angiography as bearers of coronary artery disease and non bearers individuals with coronary artery disease, while a third group was set by donors of blood in the same region. The patients' ages ranged from 36 to 84 years old, while the third group ranged from 18 to 55 years old. The genomic DNA was extracted with Amersham Pharmacia Biotech’s Kit, and the characterization of alleles involved in the change G1691A (factor V Leiden), the prothrombin G20210A, and G1793A of MTHFR C677T determined by gene amplification, followed by the performance of restriction enzyme, in accordance with established protocol...

A doença arterial coronariana representa uma das principais causas de morbidade e mortalidade das populações, principalmente naquelas que habitam regiões desenvolvidas. Os considerados fatores de risco para o desenvolvimento dessa doença são bastante conhecidos e analisados, sendo verificada uma importância cada vez maior com relação aos riscos genéticos e a verificação da associação de sistemas polimórficos humanos com a propensão a desenvolver uma determinada doença. A partir desses estudos foi possível imaginar a ocorrência dos denominados marcadores genéticos, onde os autores realizam uma tentativa com vistas às possibilidades de correlacionar esses marcadores com a doença analisada. Foi propósito do presente trabalho estabelecer e verificar a validade para o nosso laboratório de uma metodologia molecular capaz de caracterizar a mutação G1691A no gene do fator V da coagulação, a mutação G20210A no gene da protrombina e as mutações C677T e G1793A no gene da metilenotetrahidrofolato redutase. Com essa possibilidade, verificar e correlacionar as freqüências dessas mutações em portadores de doença arterial coronariana, de não portadores de doença arterial coronariana e em doadores de sangue em uma parcela da população paulista. Para tanto foram estabelecidos três grupos de estudo constituídos por moradores da região de São José do Rio Preto, Estado de São Paulo, sendo dois deles classificados por cinecoronariografia como portadores de doença arterial coronariana e como não portadores de doença arterial coronariana, enquanto um terceiro grupo foi constituído por doadores de sangue da mesma região. A idade dos pacientes variava dos 36 aos 84 anos de idade, enquanto a do terceiro grupo variava dos 18 aos 55 anos de idade...
