Age- And Gender-Based Predisposition Of MMP-9 -1562  C  & gt;  T Genotype And Allele Frequencies With Serum MMP-9 Levels As Probable Risk Factors In Patients With Coronary Artery Disease

AbstractCoronary artery disease (CAD) is the third foremost reason of death worldwide in both men and women of different age groups, and is associated with 17.8  million mortalities annually due to unknown specific genetic background. Hence, we elucidated the age- and gender-based predisposition of MMP-9 -1562 C >  T (rs3918242) genotype and allele frequencies along with serum MMP-9 levels as probable risk factors in the development of CAD. This case-control study comprised 150 CAD patients and 150 controls from the South Indian Population. PCR-RFLP was performed to determine different genotypes of MMP-9 ge ne and serum levels of MMP-9 were measured using ELISA. Age- and gender-based subgroup analysis was performed to assess the probable risk of genotype-based serum MMP-9 levels. CT heterozygote showed 25.4% increased frequency in overall CAD patients compared to controls (OR, 4.48; p <  0.0001); while it was 29.2% in men patients (OR, 6.68; p <  0.0001). The CT heterozygote incurred 25.2% increased risk of CAD in younger patients (p = 0.0033), and 25.6% in older patients (p = 0.001). Allele frequency analysis revealed 20% increased risk of minor T allele in younger patients (p = 0.001), and was 13% higher compared to older pa tients (p = 0.04). Patients with CC homozygote and CT heterozygote showed significantly increased serum MMP-9 levels. Further, comparative analysis showed significantly increased MMP-9 serum levels in women with CT...
