| Phylum | Soft Tissues::Inflammatory myofibroblastic tumor |
| WHO/OMS Classification | Soft Tissues |
| Clinics and Pathology |
| Disease | Inflammatory myofibroblastic tumors |
| Clinics | rare soft tissue tumour found in children and young adults |
| Pathology | spindle cell proliferation with myofibroblastic differenciation and an inflammatory infiltrate |

| Genes involved and Proteins |
| Gene Name | ALK (anaplastic lymphoma receptor tyrosine kinase) |
| Location | 2p23.2 |
| Protein | 1620 amino acids; 177 kDa; glycoprotein (200 kDa mature protein) ; membrane associated tyrosine kinase receptor |
| Gene Name | CLTC (clathrin heavy polypeptide) |
| Location | 17q23.1 |
| Protein | 1675 amino acids, 191 kDa; mediate endocytosis of transmembrane receptors. |
| Result of the chromosomal anomaly |
| Hybrid Gene | |
| Description | 5' CLTC - 3' ALK |
| Fusion Protein | |
| Description | 2196 amino acids. 1634 N-term amino acid from CLTC, containing nearly all of CLTC, including the triskelion assembly domain, fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain). |
