Abstract
BACKGROUND: Aspirin is an antiplatelet drug commonly administered as primary and secondary prophylaxis to prevent thromboembolic events. However, there has been a common incidence of aspirin resistance that leads to a recurrent cerebrovascular disease. One of the causes of such event is the genetic polymorphisms of the integrin alpha-2 (ITGA2) gene that encodes the glycoprotein Ia (GPIa) receptor in the pharmacodynamics of aspirin. AIM: This study analyzed the genetic polymorphism of ITGA2 as the GPIa collagen receptor encoding gene of aspirin therapy among healthy Javanese, the largest ethnic group in Indonesia. METHODS: This cross-sectional study involved 100 respondents who met the inclusion criteria with their blood sample taken for DNA isolation. Identification of genetic polymorphism in the target SNPs was done using the PCR-RFLP method with 5’-CCTTAAAGCTACCGGCCCATGT-3’ forward primer and 5’-TTGGCCTATTAGCACCAAAACTTACC-3’ reverse primer as well as Hpy188Irestriction enzyme to fragment the target at position 244 in the C base. RESULTS: This study found that the dominant genotype and allele were CT (51%) and C (66.5%), respectively. CONCLUSION: The allele frequency of ITGA2 gene in this study was similar to that of the populations in other Asian countries. Further research regarding the effects of ITGA2 C807T polymorphism on the pharmacodynamics of aspirin as an antiplatelet is recommended to minimize atherothrombotic events and examine its interactions as a biomarker of the risk and prognosis of some cancer types.
