Coronary artery disease (CAD) is a multifactorial disorder influenced by both genetic and clinical risk factors. Lipid metabolism genes such as apolipoprotein B(APOB) (rs515135) and proprotein convertase subtilisin/kexin type 9 (PCSK9)(rs505151), have been associated with susceptibility to CAD. Study investigates the potential role of these genetic polymorphisms with risk of CAD in the Indian population. A case-control study including 150 CAD cases and 150 controls. Angiographically proven Cases were recruited from the Cardiology Unit, Department of Medicine, Era's Lucknow Medical College. Genotyping was done using specific primers and restriction digestion; statistical analysis included t-tests, odds ratios, and haplotype analysis. CAD cases(mean age 49.93 ± 9.13 years) had higher serum cholesterol and VLDL but lower systolic and diastolic BP compared to controls (mean age 56.47 ± 9.39 years). The APOB G allele showed a significant protective effect against CAD (OR: 0.431, The APOB G allele may serve as a protective factor against CAD, highlighting its potential role in genetic screening for lower disease risk. Further large-scale studies are required to confirm these findings. Show less
