Background and Aims: The occurrence of anti-tuberculosis drug-induced hepatotoxicity (ATDH) deserves our attention. To explore the role of ATP-binding cassette B6 (ABCB6) polymorphisms and serum levels in the risk of antituberculosis drug-induced hepatotoxicity (ATDH).
Methods: A 1:4 matched case‒control study was conducted. Four single nucleotide polymorphisms (SNPs) and serum ABCB6 levels were analyzed, and false discovery rate (FDR) was performed to correct for multiple comparison.
Results: 224 ATDH cases and 896 controls were included. SNP rs1109867 in ABCB6 gene had a decreased risk of ATDH under dominant models (FDR corrected p-value = 0.027). Furthermore, serum ABCB6 levels at three different times in the ATDH cases were higher than those in the controls.
Conclusions: SNP rs1109867 in ABCB6 gene may contribute to the susceptibility to ATDH among patients receiving anti-TB treatment.
