Camus et al. [44] developed digital PCR (dPCR) assays for the detection of exportin-1 (XPO1) E571K, EZH2 Y641N, and MYD88 L265P mutations in DLBCL patients, in order to identify patients most likely to benefit from targeted therapies. The gene discussed is XPO1; the disease is diffuse large B-cell lymphoma.
