TCL6 and triple-A syndrome: It should be noted that some of the lncRNAs investigated in the present study, such as TCL6, LINC0892, and IL21-AS1, were reported to be involved in metastasis and tumor progression [37,38] and in other pathological conditions such as preeclampsia [39,40]; however, this is the first study involving these selected lncRNAs in AAA.
