One study found that deletions of the CDKN2A locus occur in about one-third of DLBCL patients.<sup>1</sup> The mutation pattern in DLBCL and FL implies the preferential accumulation of *inactivating mutations*. This gene has some recurrent sites of mutations (hotspots) with the most common mutation causing a truncation at codon 80 (R80*). |

| 9 | -Mutations in GNA13, which encodes a G protein alpha subunit involved in multiple signaling pathways, have been identified as significant contributors to the pathogenesis of germinal centre-derived B-cell lymphomas, including diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL).<sup>1</sup> This gene has some recurrent sites of mutations (hot spots). Overall, mutations are often loss-of-function in nature, disrupting the normal activity of GNA13. GNA13 regulates B-cell homing and growth suppression within the germinal center niche and its loss of function promotes lymphoma development.<sup>2</sup> |
