Association of <i>CYBA G640A</i> variation with coronary artery disease in Indians

<p><b>Introduction</b>: Oxidative stress induces atherosclerosis by triggering an inflammatory cascade within the vascular wall.</p> <p><b>Objective</b>: To investigate the role of pro-oxidant and antioxidant gene variations with CAD in Indian subjects.</p> <p><b>Materials & methods</b>: It’s a case-control study and genotyping for the variants <i>MPO G-463A, CYBA G640A, SOD2 Val16Ala</i> and <i>CAT C-262T</i> were performed by conventional PCR techniques.</p> <p><b>Results</b>: Only <i>CYBA G640A</i> variant allele was found to be significantly (<i>p</i> = 0.0075) associated with CAD.</p> <p><b>Conclusion</b>: Although <i>CYBA G640A</i> variation was found to be significant, a larger study is needed to validate these results and establish its role as a biomarker.</p
