As the premalignant IGH::BCL2‐positive B‐cell clone persists and continues to expand through the germinal centre reaction, this may result in additional malignant transformation, giving rise to a new lymphoma, such as transformed FL or relapsed FL, and occasionally also other low‐grade B‐cell lymphomas [3, 4, 5, 6, 7, 8]. The gene discussed is BCL2; the disease is lymphoma.
