LMO2 pin



Methodology: IHC

Clinical Significance:
Identifies: A cysteine-rich protein that also plays a central and crucial role in hematopoietic development. In the setting of diffuse large B-cell lymphomas (DLBCLs), LMO2 has high sensitivity in differentiating between germinal center B-cell (GCB) DLBCLs and non-GCB DLBCLs. Based on the recently published Tally Method algorithm, LMO2 will be used in a panel, along with CD10, GCET1, MUM1, and FoxP1, to help distinguish between GCB versus non-GCB origin among DLBCLs. Subcellular Localization: Nuclear
