In MG patients without thymoma versus healthy controls, 36 lncRNAs had 127 ‘cis’ genes upstream or downstream of their chromosomal position: lncRNA oebiotech_22652 had the highest number of ‘cis’ genes and the aberrantly expressed lncRNA oebiotech_11933 had 3 ‘cis’ genes (C1orf74, G0S2, and TRAF3IP3). This evidence concerns the gene TRAF3IP3 and thymoma.
