Polimorfismos asociados a disfunción endotelial y a un estado protrombótico en jóvenes mexicanos con infarto cerebral

Abstract

To examine the contribution the polymorphisms G20210A, G1691A and G10976A in the coagulation factors FII, FV, FVII, respectively; Glu298Asp and C677T in eNOS and 5,10 MTHFR in young Mexican population with cerebral infarction (CI). 224 patients ≤ 45 years of age with CI and 224 controls matched by age and gender were recruited from 2006 and 2014. The polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism. We identified a significant difference in the genotype distribution of Glu298Asp (p = 0.001) and C677T (p = 0.01) polymorphisms between CI patients and control groups. The genotype distribution in the FII G20210A, FV G1691A and FVII G10976A polymorphisms were similar. There were independent factors for ischemic stroke: Glu298Asp and C677T polymorphisms, smoking; hypertension, and familial history of thrombotic disease. The Glu298Asp and C677T, but not FII G20210A, FV G1691A and FVII G10976A polymorphisms were associated with CI. Our results suggest that endothelial dysfunction and the synergist interaction with other factors such as smoking and hypertension contribute to CI in young individuals.
