SLC11A1 and tuberculosis: Table 4 shows the association test results when considering TB caused by Mtbss. A single significant missense variant, rs17235409 in the SLC11A1 gene, under a homozygous recessive model of inheritance appeared to confer protection against TB infection (PBH = 0.04), whereas another SNP (rs8028149), under a dominant model of inheritance, was found tending to decrease the risk of Mtbss infection (PBH = 0.09).
