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
ICD-Morpho 9975/3 Chronic myelogenous leukaemia, BCR-ABL1 positive; Myeloproliferative neoplasm, unclassifiable; Myelodysplastic/myeloproliferative neoplasm, unclassifiable

Atlas_Id 1116
Note Only one case of t(11;11) with NUP98-DDX10 fusion has been described; most cases are cases of inv(11)

Clinics and Pathology

Disease de novo Myelodysplastic syndromes (MDS) and Acute Non Lymphoblastic Leukemias (AML), therapy related MDS and AML, one case of Chronic Myelogenous Leukemia (CML).
Epidemiology Thirteen cases reported to date: six adults and seven children (9M/4F)

Cytogenetics

 
  A: inv(11)(p15q22) Q-banding: the derivative chromosomes are on the right of each pair.
 
  B: FISH with NUP98 PAC 1173K1 probe. A split signal indicates pericentric inversion in the der(11). C: Cohybridization of DDX10 centromeric BAC RP11-976P22 (red) and subtelomeric 11p RP11-534I22 probe (green).
Additional anomalies Sole anomaly in 8 out of 13 cases

Genes involved and Proteins

Gene Name NUP98
Location 11p15.5
Protein Nucleoporin 98, a 98 kDa component of the nuclear pore complex involved in nucleo-cytoplasmic transport.
Gene Name DDX10
Location 11q22
Dna / Rna Alternative splicing; 3.2 and 5.0 kb mRNA.
Protein Putative DEAD-box RNA helicase involved in ribosome biogenesis.

Result of the chromosomal anomaly

Hybrid gene
Description 5' NUP98 - 3' DDX10
Twelve out of 13 cases present exon 14 of NUP98 fused in-frame to exon 7 of DDX10, one case with exon 12 of NUP98 fused in-frame to exon 6 of DDX10.
  
Fusion Protein
Description It fuses the GLFG repeat domains of NUP98 to the acidic domain of DDX10.
  

To be noted
