Multivariate analysis, considering only 31 NXP2+ LB+/IP+ and 211 NXP2− cases, confirms that anti-NXP2 antibodies are associated with DM (p = 0.04; OR 6.17, 95% CI 1.07–35) whilst a negative association was confirmed for ILD (p = 0.048; OR 0.08, 95% CI 0.007–0.9). Here, MORC3 is linked to dermatomyositis.
