While not reaching genome-wide significance, the HLA class l locus is also indirectly tagged through the association with rs2621322, in the TAP2 (transporter 2, ATP binding cassette subfamily B member) gene, a transporter protein that restores surface expression of MHC class I molecules and has previously been implicated in TB susceptibility (Thu et al., 2016). Here, TAP2 is linked to tuberculosis.
