| Outline of Final Research Achievements |
We have set up the Asian network to study human genetics factors associated with tuberculosis with common protocol. NAT2 slow acetylator status is confirmed as a risk factor of anti-tuberculosis drug-induced liver injury (ATDILI) in Thailand, Japan, and Indonesia. We conducted the first meta-analysis of NAT2 genotypes and risk of ATDILI and demonstrated that NAT2 ultra-slow acetylator status will have the significant effect on the increased risk of ATDILI, which has not been clear in the country-based analyses due to the small sample size. In addition, we have developed new statistical approach, logic regression, and long multigene haplotype analysis and proved their utility by our GWAS (genome-wide association study) data.
