Abstract

Background: Many different genetic associations with premature coronary artery disease (PCAD) have been identified. One exonic single nucleotide polymorphism (SNP) rs5888 of Scavenger receptor class B type1 (SCARB 1) gene has been linked to lipid traits as well as subclinical atherosclerosis. Objective: To investigate the association between SNP rs5888 of SCARB 1 gene and PCAD risk and severity. Patients and Methods: This study was conducted on 50 Egyptian patients diagnosed as PCAD by coronary angiograph (PCAD group) and (50) age- and sex-matched non-CAD subjects who showed no luminal stenosis in coronary angiographic served as a control group (non-CAD group). Gensini score was calculated as an indication for atherosclerosis severity for patients only. Detection of rs5888 polymorphism of SCARB 1 gene was done by realtime polymerase chain reaction (PCR) and high resolution melting analysis (HRM). Results: The mutant TT and CT genotypes were more frequently distributed in PCAD group compared to nonPCAD group (34 % and 48 % vs. 26 % and 18 %, respectively). The (CT) genotype conferred a positive risk for PCAD in males (OR: 6.117, 95% CI (1.744-21.452); p < 0.01). T allele conferred a positive risk for PCAD (OR: 2.564, 95% CI (1.440-4.543); p < 0.05). Highest Gensini score was found in PCAD patients with (TT) genotype (p < 0.01). Conclusion: The mutant (CT) genotype and the T allele of SCARB 1 SNP rs5888 were associated with increased risk of PCAD and the mutant (TT) genotype was associated with disease severity calculated by Gensini score.
