In addition, we selected the genes related to PID CXCR4 pathway, VEGFA–VEGFR2 signalling, cytokine signalling in immune system and regulation of lymphocyte activation pathways and showed their expression through heatmaps, and most of the genes of these pathways are significantly upregulated in MMD patients (Figure S10I). The gene discussed is KDR; the disease is multiminicore myopathy.
