PRSS3 and diffuse large B-cell lymphoma: To verify the accuracy of the top five genetic variants identified from our exome sequencing data (LNP1, PRSS3, MUC3A, FADS6, and TRAK1), we performed Sanger sequencing (Primer sequences were listed in S6 Table) of 11 our EBV+ DLBCL samples, as well as an additional 16 EBV+ DLBCL samples from another hospital (S7 Table).
