| Classification |
| renal cell carcinoma (RCC) are classified into two main clinico-pathologic entities (chromophobic/oncocytic entity excluded): |
| Clinics and Pathology |
| Disease | renal cell carcinoma |
| Phenotype / cell stem origin | t(X;1) is found in papillary renal cell carcinoma (WHO classification) |
| Epidemiology | 12 reported cases, herein reviewed; mean age 16 yrs (range 1-30); sex ratio: 7M/5F (female cases are found, contrarily to what has previously been suspected) |
| Pathology | t(X;1) appears to delineate a distinct subgroup of chromophilic papillary renal cell carcinoma with clear cell features. |
| Treatment | radical nephrectomy |
| Prognosis | similar to that of others papillary renal cell carcinoma i. e. overall 5-yr survival rate around 85%. |
| Cytogenetics |
| Cytogenetics Molecular | +7, +17 |
| Probes | TFE3 and PRCC/TFE3 |
| Variants | t(X;17)(p11.2;q25) and t(X;1)(p11.2; p34) |
| Genes involved and Proteins |
| Gene Name | TFE3 |
| Location | Xp11.2 |
| Protein | transcription factor; binds to the immunoglobulin enhancer |
| Gene Name | PRCC |
| Location | 1q21.2 |
| Protein | 491aa; widely expressed ; proline rich. |
| Result of the chromosomal anomaly |
| Hybrid Gene | |
| Description | 5' TFE3 - 3' PRCC and 5' PRCC - 3' TFE3 |
| Detection | positional cloning; screening in a tumor cDNA library and hybridization with TFE3 |
| Fusion Protein | |
| Description | PRCC/TFE3 fusion protein includes the transcription activating, helix-loop-helix and leucine-zipper domains of TFE3; the TFE3/PRCC fusion protein (513 amino acids) is also expressed |
| To be noted |
| We have had a t(X;1) case in a non-papillay renal cell carcinoma, suggesting that t(X;1) is not restricted to the papillary subtype of RCC (unpublished). |
