In another study that investigated lncRNA expression in chronic graft-versus-host disease, three lncRNAs (NONHSAT142151, NONHSAT040475 and FR118417) were found to strongly correlate with the expression of mRNAs related to the BCR signaling pathway (BTK, CD72, DAPP1, LILRB3, NFKBIE, RASGRP3). The gene discussed is BTK; the disease is chronic graft versus host disease.
