FMO2 and tuberculosis: FMO2 (flavin containing dimethylaniline monoxygenase 2) gene, located on chromosome 12 of sheep, has a physical position between 36833449 and 36833580 bp.The human FMO2 gene has been confirmed to regulate oxidative stress levels (Henderson et al., 2008), thus playing a role in innate immunity against microbial infections, including tuberculosis (Mekonnen and Bekele, 2017).
