| Atlas_Id | 1347 |
| Clinics and Pathology |
| Disease | Acute myeloid leukaemia (AML), FAB M2 subtype |
| Epidemiology | Only one case to date, a 59-year-old female patient |
| Prognosis | The patient died 5 months after the onset of the leukaemia. |
| Cytogenetics |
| Additional anomalies | +8 and other anomalies |
| Genes involved and Proteins |
| Gene Name | ETV6 (ets variant 6) |
| Location | 12p13.2 |
| Protein | ETS-related transcription regulator |
| Gene Name | NTRK3 (neurotrophic tyrosine kinase, receptor, type 3) |
| Location | 15q25.3 |
| Protein | Tyrosine kinase cell surface receptor |
| Result of the chromosomal anomaly |
| Description | 5' ETV6-3' NTRK3 |
| Description | Encodes a fusion protein with the sterile alpha motif (SAM) oligomerization domain of ETV6 in N-term to the C- term protein tyrosine kinase (PTK) domain of NTRK3 |
| Oncogenesis | Functions as a constitutively active tyrosine kinase. ETV6-NTRK3 is capable of homodimerization, or heterodimerization with ETV6, and subsequent PTK activation, leading to constitutive elevation of cyclin D1, and increased cell cycle progression. ETV6-NTRK3 also leads to constitutive activation of two of the major effector pathways of NTRK3: the Ras-MAPK mitogenic pathway and the phosphatidyl inositol-3-kinase (PI3K) pathway leading to activation of the AKT cell survival factor (Lannon and Sorensen, 2005). |
| To be noted |
| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. -The same translocation t(12;15)(p13;q25) with the same genes involved (ETV6-NTRK3) can also be found in: Secretory Ductal Breast Carcinoma , in Congenital Mesoblastic Nephroma, and in Congenital Fibrosarcoma. |
