| Disease | acute undifferentiated leukemia (AUL) |
| Epidemiology | only one case described so far |
| Cytogenetics |
| Note | the only SET-NUP214 positive case described so far had a normal karyotype; on the cytogenetic level it is unclear if the SET-NUP214 fusion is generated by a t(9;9)(q34;q34) or an interstitial deletion at 9q34; the latter is supported by the centromere-telomere orientation of both genes and their local order: centromere-SET-NUP214-telomere |
| Cytogenetics Morphological | the single case described so far had a normal karyotype; may be overlooked |
| Genes involved and Proteins |
| Gene Name | SET |
| Location | 9q34 |
| Dna / Rna | 8 exons spanning 6,81 kb of genomic DNA; 2559 bp mRNA |
| Protein | two isoforms; isoform 1 (TAF1 alpha) 290 amino acids, 33.5 kDa; isoform 2 (TAF1 beta) - 277 amino acids, 23.1 kDa; DNA associated, transcription factor; multitasking protein, involved in apoptosis, transcription, nucleosome assembly and histone binding; cytoplasmic and nuclear; in the cytoplasm, found both in the cytosol and associated with the endoplasmic reticulum |
| Gene Name | NUP214 |
| Location | 9q34 |
| Dna / Rna | 36 exons encompassing about 108 kb of genomic DNA; 6.6 kb mRNA |
| Protein | 2090 amino acids, 213.8 kDa; forms homodimers, contains two leucine zipper dimerization domains, and FG repeats at the C-terminus, which are homologous to those observed in other members of the nucleoporin family; expressed in thymus, spleen, bone marrow, kidney, brain and testis, but hardly in all other tissues or in whole embryos during development; may serve as a docking site in the receptor-mediated import of substrates across the nuclear pore complex (NPC); intracellular localization, cytoplasmic face of the NPC |
| Result of the chromosomal anomaly |
| Transcript | 5' SET - 3' NUP214 |
| Description | the SET-NUP214 fusion protein consists of almost the whole SET protein fused to the C-terminus of NUP214; 155 kDa |
| Oncogenesis | SET-NUP214 leads to disorganization of nuclear export |
