Xp11.2 tRCC was classified as “the microphthalmia transcription factor/transcription factor E (MiTF/TFE) family translocation carcinoma” by Argani and Ladanyi.13 Other MiTF/TFE family translocation carcinoma members include alveolar soft part sarcoma (ASPS) and perivascular epithelioid cell tumors (PEComas). This evidence concerns the gene MITF and renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions.
