The authors analyzed MYD88/CD79B mutations through NGS or allele-specific PCR, MYC/BCL2/BCL6 rearrangements by FISH, and EBV infections by EBER-ISH, identifying MYD88 and CD79B mutations in 29.6% and 12.3%, MYC, BCL2, and BCL6 rearrangements in 10.6%, 13.6%, and 20.3%, and EBV in 11.7% of cases, respectively. Here, MYD88 is linked to Epstein-Barr virus infection.
