As presented in the chapter above, some lincRNAs appear to be involved in different diseases; this concerns MIAT (MS, SLE, PD and AD), H19 (RA, SLE, PD, AD), lnc-DC (MS, SLE and SS), PVT1 (MS, RA, SS), MEG9 (MS and RA), lincRNA-p21 (RA and PD), UCA1 (RA and PD), and NORAD (SS and PD) (Fig. 2). This evidence concerns the gene MEG9 and rheumatoid arthritis.
