An association study of thrombospondin 1 and 2 SNPs with coronary artery disease and myocardial infarction among South Indians.

Introduction: Thrombospondin 1 and 2 are multidomain calcium-binding extracellular glycoproteins and they play a role in platelet aggregation, inflammatory response and assembly of connective tissue extracellular matrix. The association of thrombospondins (TSP) in the pathogenesis of coronary artery disease (CAD) and myocardial infarction (MI) is well established. The association of the TSP-1 (Asn700Ser, 2210A → G, rs2228262) and TSP-2 un-translated region (UTR) (3949T → G, rs8089) gene variations among South Indian CAD and MI patients has been examined in the present study.
