Abstract
<p>A recent GWAS study found a significant association between the BUD13-ZNF259 rs964184 polymorphism, dyslipidemia and the onset of coronary disease (CAD). This variant encoding zinc finger protein (ZPR1) interacts with the receptor tyrosine kinase at cellular level, increasing oxidative stress, inflammatory response and atherogenesis. There are no studies of the effect of this variant on the Portuguese population.</p> <p><strong>Objective:</strong> Investigate the association of BUD13-ZNF259 rs964184 with dyslipidemia and its impact on CAD risk. Evaluate its impact in different age groups of our population.</p> <p><strong>Methods:</strong> A case-control study was performed with 3050 subjects (1619 coronary patients with 53.3 ±8 years; 78.9% male and 1431 controls with 52.8 ±8 years; 76.6% male) from the GENEMACOR study population. Traditional risk factors (smoking, dyslipidemia, diabetes, family history, hypertension, body mass index, alcohol consumption, physical inactivity) and others considered new, such as creatinine clearance, pulse wave velocity, homocysteine, fibrinogen, lipoprotein (a), APOB and PCR (hs) were investigated. BUD13-ZNF259 variant was genotyped and analyzed using the dominant model (CG + GG vs. CC). Bivariate and multivariate analyzes (logistic regression) were used to estimate the ORs and 95% CI, after adjusting for potential confounding factors, in 3 different age groups (<45; 45-55; >55).</p> <p><strong>Results:</strong> BUD13-ZNF259 polymorphism presented an independent and significant risk of CAD (OR=1.58; 95%CI: 1.07-2.32; p=0.019) only in the group of young coronary patients <45 years (n=482 patients). In this age group, a significant association with dyslipidemia (OR=2.04; 95% CI: 1.26-3.31; p=0.003) was shown, although a more significant association was seen in the group of patients > 55 years (OR=1.59; 95% CI: 1.14-2.19; p=0.005).</p> <p><strong>Conclusion:</strong> BUD13-ZNF259 rs964184 variant showed a significant risk for the onset of CAD in the young population (<45 years). The impact of the interaction of ZPR1 protein with tyrosine kinase (Syk) at the cellular level seems to be more relevant in young patients. This aspect may represent a possible prophylactic and therapeutic target, especially in coronary disease in young people.</p>
