In a case report of immune-mediated necrotizing myopathy (IMNM) associated with acute myeloid leukemia, anti-MORC3 antibody was detected during active myositis but disappeared after disease remission, indicating that anti-MORC antibody could be used as a diagnostic and prognostic marker of paraneoplastic IMNMs [87]. Here, MORC3 is linked to myositis disease.
