The CCL20, CD24, DEFB4A, LTF, IL12A, CXCL13, and PYDC1 mRNAs and their co-expressed immune-related lncRNAs showed down-regulated expression in thymoma patients with MG compared with thymoma patients without MG, while IL31RA mRNA and its co-expression immune-related lncRNAs showed up-regulated expression (Table 2). This evidence concerns the gene DEFB4A and myasthenia gravis.
