| Outline of Final Research Achievements |
We established the international investigation network with researchers in Japan, South Korea, Singapore, Hungary, and Brazil to elucidate the genetic risk factor for venous thromboembolism (VTE). Protein S Tokushima mutant allele is found in 4.2% of Japanese VTE patients, PC p.Arg189Trp mutant allele is in 20.5% of Singaporean patients, and PC p.Lys193del mutant allele is in 2.5%, 5.5%, 7.2% of Japanese, South Korean, and Singaporean patients, respectively, however neither of these mutant alleles was found in Hungarian and Brazilian patients, indicating the racial differences in genetic risk factors. The analyses using plasma and hepatocytes revealed that the expression of protein S and protein C is closely related with the metabolism of glucose and apolipoprotein. Finally, the protein S specific activity assay is found to be able to evaluate the thrombophilic state even on medication for direct oral anticoagulants.
