However, CGP results were used to clarify the diagnosis in only 4 (20%) of these 20 patients: 1 patient with SOCS1 truncation who was diagnosed with diffuse large B-cell lymphoma, 1 patient with STAT3 Y640R mutation who was diagnosed with T-cell large granular lymphocytic leukemia, 1 patient with ETV3–NCOA2 fusion who was diagnosed with indeterminate cell histiocytosis, and 1 patient with MPL and CALR mutations who carried a diagnosis of CLL but was additionally diagnosed with myelofibrosis based in part on these results. This evidence concerns the gene ETV3 and B-cell chronic lymphocytic leukemia.
