The objective was to evaluate role of Interleukin-6 (-174 G/C) gene promoter polymorphism and the serum level of (IL-6) in the identification of PCAD.</p><p><strong> Methodology: </strong>The case-control study carried out at Army Medical College, Rawalpindi, Pakistan, from July, 2014 to Jan, 2015 in collaboration with University College London, UK. 150 patients <45 yrs of age with > 70% stenosis, in at least one coronary vessel on angiography, were labeled as cases. While 150 subjects who were angio-negative for disease were taken as controls. Genotyping was performed using Taqman Assay while serum IL-6 was measured using Enzyme Linked Immuno-sorbent Assay (ELISA).</p><p><strong>Results:  </strong>Total 300 subjects participated in the study.  Mean ± SD age of PCAD patients was 40 ± 3.80 while in controls it was 38 ± 7.8 yrs. Serum IL-6 levels were significantly high in PCAD patients (p<0.01). In IL-6 -174 (G/C) polymorphism homozygous CC was significantly associated with occurrence of PCAD. Serum IL-6 levels were significantly higher in CC genotype subjects when compared to GC and GG (p<0.05). The serum IL-6 levels significantly correlated with the atherosclerotic burden (p<0.05). Sensitivity-specificity of IL-6 at cut off value of 3.7 ng/dl was 77% and 81% respectively.</p><p><strong>Conclusion:  </strong> IL-6 has significant diagnostic potential for PCAD with moderately high sensitivity and specificity. IL-6 (-174 G/C) polymorphism CC genotype can aid in the risk prediction of PCAD.</p><p><strong>Keywords:  Gene promoter polymorphism; Interleukin-6; Premature Coronary Artery Disease; Risk prediction;</strong></p><p><strong> </strong></p>}, number={4}, journal={KHYBER MEDICAL UNIVERSITY JOURNAL}, author={Ansari, Wafa Munir and NAVEED, ABDUL K and KHAN, DILSHAD A}, year={2016}, month={Feb.}, pages={151} }
