Introduction TFtranslocation renal cell carcinoma (TFtRCC) is a rare subtype of kidney cancer, characterized by Xp112 translocations resulting in TF fusion with various partner genes To date, more than partner genes have been identified in fusions with TF, including SFPQ, ASPSCR1, NONO, PRCC, RBM10, MED15, etc Due to the variety of partners andMost common partner genes in MiT family translocation associated renal cell carcinoma are PRCC and ASPSCR1 (ASPL) (Am J Surg Pathol 16;) Melanotic subtype generally harbors the SFPQTF fusion and rarely ARID1BTF (Am J Surg PatholIn RCC, TF translocation partners have been shown to include the ASPSCR1, SFPQ and NONO genes 3 Although RCC and ASPS have been shown to have identical ASPSCR1TF fusion transcripts, the t(X;17) translocation is consistently balanced in the former but usually unbalanced in the latter the derivative X chromosome is not seen in ASPS 4
