## Overview
3
-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> These 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>
