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 andASPS is a malignant mesenchymal tumour with an ASPSCR1TF fusion molecular signature (der(17)t(X;17)(p112;q25) translocation This results in the fusion of TF transcription factor gene at Xp112 with ASPSCR1 (also known as ASPL) at 17q25 As mentioned earlier, the same gene signature is also present in a subset of RCCs, which have aThe ASPSCR1TF gene fusion is the same gene fusion found in alveolar soft part sarcoma (ASPS), a rare pediatric neoplasm of uncertain histogenesis However, the translocation in Xp11 translocation RCC is balanced, which may contribute to the differences seen at the clinical and histopathologic levels between Xp11 translocation RCC and ASPS
When a TF rearrangement is identified, reflex testing using the TF/ASPSCR1 probe will be performed Method Name A short description of the method used to perform the test Fluorescence In Situ Hybridization (FISH)Alveolar soft part sarcoma (ASPS) is a morphologically distinctive neoplasm of unknown differentiation that bears a characteristic gene fusion involving ASPSCR1 and TFASPS can occur in the female genital tract, but is rare Eleven cases with an initial diagnosis of ASPS at female genital tract sites were evaluated for their morphologic features and immunoprofile using a panelTF is also expressed in alveolar soft part sarcoma the hallmark of which is a chromosomal rearrangement at 17q25 and Xp112 engendering an ASPSCR1–TF fusion gene Use of this antibody is an aid in the recognition of Xp11 translocation renal cell carcinoma and alveolar soft part sarcoma within the context of an antibody panel
ASPSCR1 Tether containing UBX domain for GLUT4 ( TUG) is a protein that in humans is encoded by the ASPSCR1 gene This gene is a candidate gene for alveolar soft part sarcoma (ASPS) It has been found that ASPSCR1 can undergo oncogenic rearrangement with transcription factor TF gene, creating an aberrant gene that is a strongerThese include ASPSCR1–TF in all cases of alveolar soft part sarcoma (ASPS) and ASPSCR1–TF, PRCCTF, SFPQTF and others in a subset of paediatric and adult RCCs Here we examined the functional properties of the ASPSCR1–TF fusion oncoprotein, defined its target promoters on a genomewide basis and performed a highthroughput RNAOur results demonstrate that the most sensitive marker of alveolar soft part sarcoma was the presence of the ASPSCR1TF fusion transcript Thus, detection of the ASPSCR1TF fusion transcript was considered applicable for formalinfixed, paraffinembedded tissues with superior sensitivity as compared with TF immunohistochemical staining
The ASPSCR1TF fusion was originally identified in 100% of alveolar soft part sarcomas (ASPS), a rare lung cancer variant with no known RCC association, and the SFPQTF fusion and possibly other TFfusions are also found in a subset of rare tumors known as perivascular epithelioid cell neoplasms (PEComas) 27,28 The existence ofThe TF fusion partners in the latter three neoplasms have been fairly consistent;
