The tumor necrosis factor (TNF) receptor superfamily member HVEM (encoded by the gene TNFRSF14) is the most highly mutated surface molecule in GC-derived follicular lymphoma (FL) and diffuse large B cell lymphoma (DLBCL) (Cheung et al., 2010, Lackraj et al., 2018, Launay et al., 2012, Manso et al., 2017, Schmitz et al., 2018). Here, TNFRSF14 is linked to follicular lymphoma.
