Genetic features of precursor B-cell phenotype Burkitt leukemia with IGH-MYC rearrangement.

ABSTRACT:

Background

An atypical form of Burkitt leukemia/lymphoma (BL), BL with a phenotype of precursor B-cells (preBLL), is listed in the WHO Classification. Recent reports suggested that preBLL and classical BL could be distinguished by the differences in IG-MYC translocation architecture and an additional mutated genes profile. The characteristics of classical BL are IG-MYC by aberrant somatic hypermutation or class switch recombination, and BL-specific gene mutations such as MYC, ID3, and CCND3. Meanwhile, preBLL is characterized by IG-MYC due to aberrant VDJ recombination and mutations in NRAS and KRAS. However, it is not clear whether all preBLL cases can be differentiated. This report investigated the molecular characteristics of an infant preBLL case, with a more advanced stage of
