Abstract
IGH rearrangements are a common chromosomal abnormality seen in lymphoproliferative disorders, including ALL. Numerous translocation partners of IGH gene have been identified. Here we report a B-ALL case with a t(14;17)(q32;q21) IGH/IGF2BP1.
Clinics and Pathology
Disease
B-cell acute lymphoblastic leukemia (ALL)
Phenotype stem cell origin
CD10+, CD19+, CD38+, cytoplastic CD22+ ALL
Epidemiology
Only one case, a 16 year old boy (Gu et al., 2014)
Clinics
Severe pancytopenia and an elevated lactate dehydrogenase (1048U/L); WBC was 2.7 X 10 9 with 20% blasts; no central nervous system involvement.
Genes Involved and Proteins
Gene name
IGH (Immunoglobulin Heavy)
Location
14q32.33
Gene name
IGF2BP1 (insulin-like growth factor 2 mRNA binding protein 1)
Location
17q21.32
Protein description
IGF2BP1 is a member of Insulin-like growth factor 2 mRNA-binding protein family; pro-oncogenic RNA-binding; post-transcriptional regulation of gene expression (Bell et al., 2013; Lederer et al., 2014).
Result of the Chromosomal Anomaly
Description
likely head-to-head fusion of IGF2BP1 with the IGH locus.
Oncogenesis
Overexpression of the IGF2BP1 gene.
