| 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. |
| Keywords | IGH partner, t(14;17)(q32;q21), IGF2BP1, acute B lymphoblastic leukemia |

| Clinics and Pathology |
| Disease | B-cell acute lymphoblastic leukemia (ALL) |
| Phenotype / cell stem 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. |
| Cytogenetics |
| Cytogenetics Morphological | An additional copy of the derivative 14 was found |
| 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 | 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. |
| To be noted |
| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. |
