Correlation between lncRNA AC079767.4 variants and liver injury from antituberculosis treatment in West China

Antituberculosis drug-induced adverse drug reactions (ADRs) has been attached the increasing attention currently. And many host genetic determinants of ADRs have been identified. However, the possible relationship between long non-coding RNA (lncRNA) and ADRs is little investigated in tuberculosis (TB). We conducted a prospective survey and comprehensively collected the information of diverse ADRs during antituberculosis therapy. Next, we analyzed whether single nucleotide polymorphisms (SNPs) within lncRNA AC079767.4 gene are associated with ADRs development of patients with TB. Our results showed that the overall occurrence rate of ADRs due to TB treatment was 16.39% (70/427), of which the anti-tuberculosis drug-induced hepatotoxicity (ATDH) constituted the most common adverse events with prevalence rate of 12.88% (55/427). Notably, TB patients carrying T allele-containing genotypes in rs1055229 locus potentially presented a greater risk (1.85-fold, 95%CI = 1.04-3.28) for developing ATDH when compared with those CC genotype carriers, 17.28% versus. 10.19%, respectively, with the age- and gender -adjusted p-value of 0.035. Our data suggest that the ADRs exhibit serious morbidity in TB patients in West China, and for the first time we show that the AC079767.4 rs1055229 is a potential genetic risk component for ATDH development. Further studies on larger population and other ethnic groups are needed to confirm our results.
