Clinics and Pathology

Disease B cell acute lymphoblastic leukemia (B-ALL)
Note An apparently identical t(13;19)(q14;p13) has been described in 3 cases of chronic lymphocytic leukemia (CLL) (Finn et al., 1998; Merup et al., 1998; Brown et al.,1993).
Epidemiology Only one case to date of ALL with this translocation, a 19-year-old female patient with pre-B-ALL; she achieved complete remission and (CR) was in continuing CR 10 months later, at last follow up (Barber et al., 2007).

Genes involved and Proteins

Note The translocation involves TCF3 and an unknown partner.
Gene NameTCF3 (transcription factor 3 (E2A immunoglobulin enhancer binding factors E12/E47))
Location 19p13.3
Protein The E2A gene encodes two distinct basic helix-loop-helix transcription factors, E12 (ITF1) and E47 (TCF3) through alternative splicing. It forms homodimers and heterodimers with other basic helix-loop-helix transcription factors. Ubiquitously expressed during development. Role in cell growth, cell commitment, and differentiation. Role in epithelial mesenchymal transition (review in Slattery et al., 2008).

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
