| Clinics and Pathology |
| Disease | previously diagnosed as papillary renal cell carcinoma, they share cytogenetic features with alveolar soft part sarcoma, and they exibit pathological characteristics of one or the other tumours, or intermediate features. |
| Epidemiology | mainly found in young patients (1.5 yr to 17 yrs in a series). |

| Treatment | surgery |
| Prognosis | relatively indolent clinical course. |
| Cytogenetics |
| Cytogenetics Morphological | balanced t(X;17)(p11.2;q25). This is in contrast with what is found in the alveolar soft part sarcoma where the tranlocation t(X;17)(p11.2;q25) involves the same breakpoints and the same genes, but is found unbalanced in most, if not all, the cases |

| Genes involved and Proteins |
| Gene Name | TFE3 |
| Location | Xp11 |
| Dna / Rna | 8 exons |
| Protein | transcription factor; member of the basic helix-loop-helix family (b-HLH) of transcription factors primarily found to bind to the immunoglobulin enchancer muE3 motif |
| Gene Name | ASPSCR1 |
| Location | 17q25 |
| Protein | 476 amino acids; contains an UBX domain |
| Result of the chromosomal anomaly |
| Hybrid Gene | |
| Description | 5' ASPSCR1-3' TFE3;. ASPSCR1 is fused in frame to TFE3 exon 3 or 4 the reciprocal 5' TFE3 - 3' ASPSCR1 may or may not be transcribed |
| Fusion Protein | |
| Description | NH2 term from ASPSCR1, fused to the C term of TFE3, including the activation domain, the helix-loop-helix, and the leucine zipper from TFE3 |
