Although numerous studies have shown that the single-nucleotide polymorphisms (SNPs) of SLC11A1 were associated with the risk of TB in different populations (Wu et al., 2013; Harishankar et al., 2018; Asante-Poku et al., 2021), whether polymorphisms in and near the SLC11A1 gene are associated with susceptibility to TB in the northwest Chinese Han population has not yet been reported. The gene discussed is SLC11A1; the disease is tuberculosis.
