MARTINEZ-RIOS, Marco A. et al. Toll-like receptor 4 gene polymorphisms and acute coronary syndrome: No association in a Mexican population. Arch. Cardiol. Méx. [online]. 2013, vol.83, n.4, pp.257-262. ISSN 1665-1731.  https://doi.org/10.1016/j.acmx.2013.09.001.

Objective: The objective of this study was to establish the role of the TLR-4 gene polymorphisms in individuals in risk of developing ACS. Methods: The study included 457 Mexican patients with ACS and 283 control individuals. The TLR-4 Asp299Gly and TLR-4 Thr399Ile single nucleotide polymorphisms were genotyped using 5' exonuclease TaqMan genotyping assays on an 7900HT Fast real-time PCR system according to manufacturer's instructions (Applied Biosystems, Foster City, USA). Results: The results obtained in this study showed that the frequency of the two polymorphisms (TLR-4 Asp299Gly and TLR-4 Thr399Ile) studied were similar between patients with ACS and healthy controls. Multiple logistic regression analysis showed that the largest risk factor for ACS development was given by smoking (11.88-fold increased risk), hypertension (4.32-fold increased risk), type II diabetes (3.44-fold increased risk), gender (2.32-fold increased risk), and dyslipidemia (1.52-fold increased risk). Conclusion: The Asp299Gly and Thr399Ile polymorphisms were not associated with susceptibility to ACS in the Mexican population.
