In Asians, no genetic model revealed correlation between PTPN22-C1858T polymorphism and increased susceptibility to mycobacterial infection [C versus G: OR = 0.22 (95% CI: 0.08–0.64, PH = 0.470); CT versus CC: OR = 1.03 (95% CI: 0.21–4.97, PH = 0.001); CT+TT versus CC: OR = 1.03 (95% CI: 0.21–4.97, PH = 0.001)] (Table 2). Here, PTPN22 is linked to Mycobacterium infection.
