In MG patients with versus without thymoma, 58 lncRNAs had 271 ‘cis’ genes upstream or downstream of their chromosomal position: lncRNA oebiotech_22652 had the highest number of ‘cis’ genes, whereas lncRNA oebiotech_12244 had 6 ‘cis’ genes(PPBP, CXCL1, CXCL5, PF4V1, PF4, and C14orf45). Here, PPBP is linked to thymoma.
