Abstract Review on Renal cell carcinoma with t(X;1)(p11;p34) SFPQ/TFE3, with data on clinics, and the genes involved.


ICD-Morpho 8260/3 Papillary adenocarcinoma, NOS
Atlas_Id 5056
Phylum Urinary system: Kidney::Renal cell carcinoma
WHO/OMS Classification Urinary system
Note must not be confused with the t(X;1)(p11.2;q21), also found in renal cell carcinoma


    Xp11 translocation renal cell carcinoma (RCCs) harbor gene fusions involving TFE3 transcription factor. The The t(6;11) RCCs harbor a specific MALAT1 (Alpha) - TFEB gene fusion. TFEB and TFE3 belong to the same MiT subfamily of transcription factors. Because of similarities at the clinical, morphologic, immunohistochemical, and genetic levels, the Xp11 translocation RCCs and t(6;11) RCCs are currently grouped together under the category of MiT family translocation renal cell carcinoma.

Clinics and Pathology

Disease t(X;1)(p11.2;p34) is found in a subset of Xp11 translocation RCC, median age 36 years. These tumors often have papillary architecture and clear cells with subnuclear vacuoles mimicking clear cell papillary RCC, or a nested clear cell appearance mimicking clear cell RCC.
Phenotype / cell stem origin The identical gene fusion may be found in Xp11 translocation PEComas and Melanotic Xp11 translocation cancers, which differ from the RCC in that they are PAX8 negative and Cathepsin K positive by immunohistochemistry.

Genes involved and Proteins

Gene NameTFE3 (transcription factor E3)
Location Xp11.23
Protein Contains a transcriptional activation domain , a helix-loop-helix, and a leucine zipper; member of the basic helix-loop-helix family (b-HLH) of transcription factors.

Gene NameSFPQ (PTB-associated splicing factor)
Location 1p34.3
Protein Contains RNA binding domains; involved in pre-m RNA splicing; form complexes with DNA topoisomerase I.

Result of the chromosomal anomaly

Hybrid Gene
Description 5' SFPQ - 3' TFE3
Fusion Protein
Description N-term SFPQ and most of it fused to the DNA binding domains of TFE3 (excluding the acidic transcriptional activation domain, including the C-term helix-loop-helix, and the leucine zipper); no TFE3-SFPQ reciprocal transcript, as the der(X) t(X;1) is missing; the normal TFE3 transcript is found.
