Full Description
Bi-directional sequencing analysis on MYD88 exon 5, including detection of the common L265Pmutation. It helps differentiate lymphoplasmacytic lymphoma (LPL)/Waldenstrom Macroglobulinemia (WM) from other lymphomas, including the B-cell-like (ABC) and germinal center B-cell-like (GCB) subtypes of diffuse large B-cell lymphomas. MYD88is also implicated in susceptibility to BTK inhibitors in the treatment of B-cell neoplasms.
