Malfunctioning of nucleoporins is well known in human malignancies, such as gene fusions of NUP214 and NUP98 in hematological neoplasms and overexpression of NUP88 in a variety of human cancers.
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.
In order to gain additional clinico-hematological data and to identify new partners of NUP98, the Groupe Francophone de Cytogénétique Hématologique (GFCH) collected cases of hematological malignancies where a 11p15 rearrangement was detected.
The nucleoporin 98 kDa (NUP98) gene has been reported to be fused to 17 different partner genes in various hematologic malignancies with 11p15 aberrations.
Due to its participation in translocations leading to the formation of fusion with at least 29 different partner genes, NUP98 is considered one of the most promiscuous fusion genes in hematologic malignancies.
This report is the first of ANKRD28 as an NUP98 fusion partner, and this case implies that this fusion may be responsible for hematologic malignancies.
The NUP98 gene at 11p15 is known to be fused to DDX10, HOXA9, HOXA11, HOXA13, HOXD11, HOXD13, LEDGF, NSD1, NSD3, PMX1, RAP1GDS1, and TOP1 in various hematologic malignancies.
Chromosome translocations involving nucleoporin 98 gene (NUP98) have been identified in a wide array of hematologic malignancies, and the resulting NUP98-associated fusions are known to play a critical role in leukemogensis through dysregulation of gene expression.
