Antituberculosis drug‐induced liver injury (ATDILI) has received increasing attention globally, which may limit the effectiveness of antituberculosis (anti‐TB) treatment. Many host genetic determinants of ATDILI have been identified recently. As little knowledge is currently available about the association between aldehyde dehydrogenase 1 family member A1 (ALDH1A1) polymorphisms and ATDILI, the association between their variants and the susceptibility to ATDILI was investigated. A total of 747 patients with TB treated by first‐line anti‐TB drugs were prospectively enrolled at West China Hospital. Genomic DNA was extracted from the peripheral blood sample of each patient and seven single‐nucleotide polymorphisms (SNPs) of ALDH1A1 gene were screened and genotyped with a custom‐designed 2×48‐plex SNP Scan TM kit. The patients were followed up monthly to monitor the development of ATDILI. The C allele and the CA genotype of rs7852860 were significantly associated with an elevated risk for ATDILI (p = .006 and 0.005, respectively), which was consistent with the results in the dominant and additive models. No allele, genotype, or genetic model of the other six SNPs (rs3764435, rs348471, rs63319, rs610529, rs7027604, rs8187876) were found to be associated with susceptibility to ATDILI. The findings first demonstrate that rs7852860 variants in ALDH1A1 gene is associated with susceptibility to ATDILI in the Chinese Han population. Validation studies with larger sample sizes and other ethnic groups are needed to confirm the findings.
