PD-L1/PD-L2-involving genetic abnormalities were interrogated using targeted-capture sequencing in a total of 384 samples from different lymphoma subtypes, including DLBCL (n = 75), follicular lymphoma (FL, n = 49), mucosa-associated lymphoid tissue lymphoma (MALT, n = 20), mantle cell lymphoma (MCL, n = 32), PMBCL (n = 10), PTCL-not otherwise specified (PTCL-NOS, n = 104), and EBV-positive T-cell and NK-cell proliferations (n = 94) (Supplemental Table S1). Here, CD274 is linked to lymphoma.
