| Note |
This entity probably does not exist:
1- PSMD2 sits in 3q27, while the breakpoint is in 3q21;
2- PSMD2, a protein of the proteasome is well known by its alias, RPN1, while the true RPN1, a protein involved in N-glycosylation, sitting in 3q21, is better known by its full name: Ribophorin I.
The translocation is therefore likely to be t(1;3)(p36;q21) RPN1/PRDM16 |

| Disease |
Myeloid lineage (MDS, AML, therapy related AML, CML, MPD); features similar to those of the 3q21q26 syndrome including normal or elevated platelet count at diagnosis, megakaryocytic hyperplasia and dysplasia. Very rarely in lymphoid lineage |
| Phenotype / cell stem origin |
of 39 cases, there were: 22 myelodysplastic syndromes (MDS) (17/22 transformed into refractory acute myeloid leukemia (AML) of -M1 or -M4 type), 8 de novo AML, 3 therapy-related MDS, 2 polycythemia vera, 1 essential thrombocythemia, 1 chronic myelogenous leukemia (CML), 1 multiple myeloma, 1 waldenstrom's macroglobulinemia |
| Epidemiology | patients are aged: 30-80 yrs |
| Clinics | Roughly 50% of patients present with MDS, another 10% with therapy associated MDS, 25% with de novo AML, and the remainder with a range of other myeloproliferative disorders. The majority of MDS patients transform into AML with a short preleukemic phase.
Blood data: frequent thrombocytosis or normal platelet count |
| Cytology | frequently characterized by dysmegakaryocytopoiesis |
| Pathology | The pathology is typical of MDS, often with a prominent monocytic component. Trilineage dysplasia. Acute leukemias that evolve usually show the morphology of M4 AML. |
| Treatment | Patients are treated with conventional chemotherapy for AML. |
| Prognosis | Very poor so far: from 16 cases, median survival was 6 mths in AML, 20 mths in MDS |
| Rearrangements of chromosome 3 involving bands 3q21 and 3q26 are associated with normal or elevated platelet counts in acute nonlymphocytic leukemia. |
