Our data indicated that the rs7117932 alleles and genotypes are associated with DM and IIMs (P <sub>c</sub> = 6.0 × 10<sup>-3</sup> and P <sub>c</sub> = 0.029; P <sub>c</sub> = 0.013 and P <sub>c</sub> = 0.019, respectively).
A significant allele association was observed in the overall IIM group vs controls for the IKBL-62T allele (rs2071592, odds ratio 1.5, 95% CI 1.21, 1.89, corrected P = 0.0086), which strengthened after stratification by anti-Jo-1 or -PM-Scl antibodies.
