Analysis of rs6725887 in the WD Repeat Protein 12 in Association with Coronary Artery Disease in Iranian Patients.

ABSTRACT: Although genetic variants that affect susceptibility to coronary artery disease (CAD) have been greatly known, a number of these single nucleotide polymorphisms (SNPs) remain to be analyzed in populations with different ethnicities. CAD is influenced by numerous genetic, environmental, and lifestyle factors, and is an important reason for mortality around the globe. In this study, a novel SNP (rs6725887) in the WD Repeat Protein 12 (WDR12) gene was selected to be examined in Iranian patients with CAD. Ninety eigth healthy controls and one hundred and one CAD patients were enrolled from Iranian population, and their clinical data were collected for further comparisons. After DNA extraction from each sample, genotypes were characterized by Taq Man probe real- time PCR assay. Statistical analyses were performed to evaluate genotype and allele frequencies and compared the values with clinical variables. Body mass index, blood pressure, fasting blood sugar, LDL, HDL, cholesterol, and triglyceride significantly differed in CAD and control groups. Genotype and allele frequencies of rs6725887 in CAD patients and controls showed no significant association in the distribution. However, clinical parameters of CAD patients like HDL, LDL, FBS, TG, DBP and SBP had significantly (P<0.05) higher levels compared to control group. The rs6725887 polymorphism is unlikely to play a key role in CAD risk in our population. Further additional samples are required for better appreciation of the influence of WDR12 SNP on CAD occurrence.

Project description:BackgroundCoronary artery stenosis induces heart diseases including acute coronary syndrome (ACS). Some studies reported the ceramide species are associated with the ACS and major adverse cardia and cerebrovascular events (MACE). However, few studies investigated the association between plasma ceramide levels and the severity of stenosis, together with the onset of diseases. This aim of the present study was to investigate the association betweencertain ceramide species, coronary artery stenosis and acute coronary syndrome.MethodsFive hundred fifty-three patients with definite or suspected CAD were recruited and received angiography. Subjects were assigned into 4 groups according to the severity of coronary artery stenosis. The measurements of 4 plasma ceramide species, namely, Cer (d18:1/16:0), Cer (d18:1/18:0), Cer (d18:1/24:1), Cer (d18:1/24:0) were carried out by Liquid chromatography-tandem mass spectrometry (LC-MS/MS) and the ratio of Cer (d18:1/16:0), Cer (d18:1/18:0) and Cer (d18:1/24:1) to Cer (18:1/24:0), respectively, were calculated as index to evaluate the association between plasma ceramides levels and coronary artery stenosis. Multiple logistic regression analysis was used to establish the prognostic model for the prediction of ACS risk.ResultsAfter the adjustment by multiple clinical risk factors including age, gender, pre-existing myocardial/cerebral infarction, hemoglobin A1c% (HbA1c%), smoking and the diagnosis during index hospitalization, multiple logistic regression analysis showed that the high ratio of Cer (d18:1/24:1) to Cer (d18:1/24:0), female gender, HbA1c%, unstable angina (UAP) and acute myocardial infarction (AMI) diagnosis (compared with atherosclerosis) during index hospitalization were associated with more severe coronary artery stenosis. Furthermore, the prognostic model was established after adjustment of risk factors and the area under curve (AUC) of receiver operating characteristics (ROC) for the prognostic model was 0.732 and 95% CI was 0.642-0.822.ConclusionThe severity of coronary artery stenosis is associated with high ratio of Cer (d18:1/24:1) to Cer (d18:1/24:0), female gender, HbA1c% and AMI. Although the reported prognostic model showed a good discrimination, further investigation on long term MACE is needed to evaluate the role of ceramide for the prediction of MACE risk.
