This is further supported in the present study, where 15% (7/47) of chemically induced murine lymphoma (13% of DLF and 16% of BLF) display somatic mutations in Bcl11b. Interestingly, all mutations are located between codon 778 and 844, with a hotspot at codon 828 where four samples show the same mutation (Table 2). The gene discussed is BCL11B; the disease is lymphoma.
