Recurrent 11q aberrations in MYC-neg mature aggressive B-cell lymphomas resembling BL


ABSTRACT: Copy number analysis using Agilent 244k or 180k (Case9) arrays was performed for 8 MYC-negative B-cell lymphomas, with sex-matched control DNAs Agilent 244k (cases 4-7 and 10-12) and 180k (Case9) arrays

The genetic hallmark of Burkitt lymphoma (BL) is the t(8;14)(q24;q32) and its variants leading to activation of the MYC oncogene. It is a matter of debate whether true BL without MYC translocation exists. Here, we identified 59 lymphomas concordantly called BL by 2 gene expression classifiers among 753 B-cell lymphomas. Only 2 (3%) of these 59 molecular BL lacked a MYC translocation, which both shared a peculiar pattern of chromosome 11q aberration characterized by interstitial gains including 1  ...[more]
