BTG2

Overview

BTG2 is one of a number of genes affected by aberrant somatic hypermutation in B-cell lymphomas, which complicates the interpretation of mutations at this locus. Mutations in the BTG2 gene have been implicated in the pathogenesis of diffuse large B-cell lymphoma (DLBCL), contributing to the development and progression of the disease. These mutations are a feature of the MCD genetic subgroup of DLBCL.1 The biological function of BTG2 mutations and their role in lymphomagenesis remains poorly understood. A potential prognostic association with BTG2 mutations in primary testicular DLBCL has been reported but this has not yet been reproduced.2
