NUP98 has not yet been associated with renal AML pathogenesis, but somatic NUP98 alterations are recurrently implicated in hematological malignancies, most often following a gene fusion event.
Chromosomal rearrangements involving NUP98 gene have been associated with human leukemias such as de novo AML, therapy-related AML (t-AML), myelodysplastic syndrome (MDS), and chronic myeloid leukemia (CML).
Furthermore, another type of NUP98-NSD1 fusion transcript was identified by additional RT-PCR analyses using other primers in a NUP98-NSD1-like patient, revealing the significance of this signature to detect NUP98-NSD1 gene fusions and to identify a new poor prognostic subgroup in AML.
Mice that express a NUP98-HOXD13 (NHD13) transgene develop a MDS that closely mimics the human condition in terms of dysplasia, ineffective hematopoiesis, and transformation to acute myeloid leukemia (AML).
NUP98-HOXA9 [t(7;11) (p15;p15)] is associated with inferior prognosis in de novo and treatment-related acute myeloid leukaemia (AML) and contributes to blast crisis in chronic myeloid leukaemia (CML).
The aim of this study was to determine the incidence of rearrangements of NUP98 (the gene coding for nucleoporin 98kDa protein) in childhood acute myeloid leukemia (AML) and selected patients with 11p13-15 rearrangements.
The cryptic translocation t(5;11)(q35;p15.5), which creates a NSD1-NUP98 fusion gene, has been associated with a deletion of the long arm of chromosome 5, del(5q), in pediatric acute myeloid leukemia (AML) patients with differentiated phenotype.
