IGHD and B-cell non-Hodgkin lymphoma: For instance, in B cell lymphoma specimen Blym1, abundant clonotypes for IGHV-IGHD-IGHJ (IGHV3-23(D)/IGHJ4), IGHD-IGHJ (IGHD2-2/IGHJ6), IGKV-IGKJ (IGKV1(D)-39/IGKJ4), IGKV-KDE (IGKV2(D)-30/KDE), and Intron-KDE were detected, although in this sample the results for IGHD-IGHJ gene rearrangement detection slightly varied between the two centres (Fig. 5).
