FISH, NHL, BCL6 3q27 Rearrangement
Order Code:
BCL63Q
Test Summary
Chromosomal rearrangements of the BCL6 gene located at 3q27 are found in B-cell non-Hodgkin lymphomas including diffuse large cell lymphoma (DLCL),follicular lymphoma (FL) and marginal zone B-cell lymphoma (MZBCL). DLCL is an aggressive disease that usually responds well to multiagent chemotherapy. Up to 30% of DLCL demonstrate recurrent rearrangements involving the BCL6 gene.
