Kidney: t(X;1)(p11.2;p34) in renal cell carcinoma

Identity

Note	must not be confused with the t(X;1)(p11.2;q21), also found in renal cell carcinoma

Classification

renal cell carcinoma (RCC) are classified into two main clinico-pathologic entities clear-cell RCC (also called non-papillary RCC, found in 80% of cases) chromophilic RCC (also called papillary RCC, in 15-20% of cases)

Clinics and Pathology

Disease	t(X;1)(p11.2;p34) is found in very rare (n<5) cases of papillary renal cell carcinoma
Phenotype / cell stem origin	may not be restricted to the papillary subtype of renal cell carcinoma

Genes involved and Proteins

Gene Name	TFE3
Location	Xp11.2
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 Name	PSF
Location	1p34
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' PSF- 3' TFE3
Fusion Protein
Description	N-term PSF 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-PSF reciprocal transcript, as the der(X) t(X;1) is missing; the normal TFE3 transcript is found
