cyclin-d1 and Coronary-Artery-Disease

Coronary artery disease (CAD) is a complex disease resulting from a combination of environmental and genetic factors. We hypothesized that polymorphisms in methylenetetrahydrofolate reductase (MTHFR) rs1801133 C/T, matrix metalloproteinases (MMPs)-2, tumour necrosis factor (TNF)-α, macrophage migration inhibitory factor (MIF) rs755622 G/C and cyclin D1 (CCND1) rs678653 G/C contribute to CAD susceptibility. We examined the association between the five polymorphisms and the risk of CAD in a Chinese population of 435 CAD patients and 480 controls. Genotyping was performed using matrix-assisted laser desorption ionization/time-of-flight mass spectrometry (MALDI/TOF MS). When the MTHFR rs1801133 CC homozygote genotype was used as the reference group, the TT or CT/TT genotypes were associated with a significantly increased risk for CAD. The CT heterozygote genotype was not associated with the risk for CAD. Logistic regression analyses revealed that MMP-2 rs243865 C/T, TNF-α rs1800629 A/G, MIF rs755622 G/C and CCND1 rs678653 G/C polymorphisms were not associated with the risk of CAD. These findings suggest that the MTHFR rs1801133 C/T polymorphism is associated with CAD development. Future larger studies with other ethnic populations are required to confirm current findings.
