Many of these secreted proteins have not been previously reported in MMD, including interleukins (IL-2, IL-4, IL-5, IL-7, IL-8, IL-9, IL-17, IL-18, IL-22, and IL-23) and C-X-C motif chemokines (CXCL1 and CXCL9) (Supplementary Table 1, *asterisks were added next to molecules that have not been previously reported in MMD). This evidence concerns the gene CXCL9 and multiminicore myopathy.
