CEACAM5 and Miyoshi myopathy: Two new lncRNAs were found to be associated with oncogenes: MSTRG.155519, a new upstream molecule in the pathway of MM, and CEACAM1, the downstream regulatory gene of MSTRG.155519, which was found through the prediction of lnc_TransTar.xlslncRNA.CEACAM1, known as CD66a (cluster of differentiation 66a), are members of the carcinoembryonic antigen family and the only CD66 abnormally expressed on the surface of plasmacytes.
