To summarize all the abovementioned information, we found that the intronic polymorphism rs3732357 in the NR1I2 gene is related to RIF plasma exposure, whereas none of the studied SNPs in the RIF-associated pharmacogenes, i.e., SLCO1B1, SLCO1B3, ABCB1, and NR1I2, was related to the anti-TB drug-induced liver injury in Latvian patients with PTB. Here, SLCO1B3 is linked to tuberculosis.
