| Identity |
| ICD-Topo | C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS |
| ICD-Morpho | 9861/3 AML with mutated NPM1; AML with mutated CEBPA; Acute myeloid leukaemia, NOS |

| Atlas_Id | 1232 |
| Note | rare abnormality |
| Clinics and Pathology |
| Disease | Acute non lymphoblastic leukemia (AML), one case of transformed chronic myeloid leukemia (CML-BC). |
| Phenotype / cell stem origin | AML FAB TYPE M1, M2, M2/M3 |
| Epidemiology | Five cases reported to date: four adults and one 5-year-old girl. |
| Prognosis | Unfavorable outcome |
| Cytogenetics |
 | |
| A) Partial Q-banded karyotype showing the t(9;11)(p22;p15); derivative chromosomes are on the right of each pair. B) FISH analysis using PAC 1173K1 (NUP98) and RP11-356J15 (PSIP1) probes (green and red signals, respectively). Arrow and arrowhead indicate the fusion signals on the der(9) and the der(11), respectively. | |
| Additional anomalies | Sole anomaly in the four AML cases, t(9;11) in addition to the t(9;22) in the CML-BC case. |
| Genes involved and Proteins |
| Gene Name | NUP98 (nucleoporin 98 kDa) |
| Location | 11p15.4 |
| Protein | Nucleoporin 98, a 98 kDa component of the nuclear pore complex involved in nucleo-cytoplasmic transport. |
| Gene Name | PSIP1 (PC4 and SFRS1 interacting protein 1) |
| Location | 9p22.3 |
| Note | The gene contains at least 15 exons and 14 introns |
| Dna / Rna | Two alternative splice variants: p75 and p52 |
| Protein | Chromatin-associated protein involved in trascriptional regulation, mRNA splicing and cell survival in vitro. Contains a PWWP domain and AT hook-like motifs. |
| Result of the chromosomal anomaly |
| Description | 5'NUP98 - 3'PSIP1; The breakpoint in the NUP98 gene is the same in three out of four cases studied (nucleotide 1230), while the breakpoints in PSIP1 are variable. |
| Description | It fuses the GLFG repeat domains of NUP98 to the COOH-terminal of the PSIP1 |
| 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. |
