Alternatively, TBL1XR1 and GPR34 mutations are frequent in salivary gland MALT lymphomas (24% and 19%) (Moody et al, 2018) and uncommon in other MALT lymphomas (Moody et al, 2018; Johansson et al, 2020; Magistri et al, 2021; Vela et al, 2022). This evidence concerns the gene GPR34 and MALT lymphoma.
