We analyzed IARS2 transcription pattern in different cancer types via GEPIA2 and detected higher expression in cholangiocarcinoma, lymphoid neoplasm diffuse large B-cell lymphoma, pancreatic adenocarcinoma, and thymoma as well as lower expression in acute myeloid leukemia compared with normal tissue (Fig. 1A, B). The gene discussed is IARS2; the disease is thymoma.
