Non Hodgkin Lymphoma (Indolent B-NHL) Panel - Wet pin


Panel Components:
IgH breakapart
t(14;18) IGH/BCL2
BCL6 breakapart
t(11;14) CCND1/IGH
* Panel makeup subject to change

Methodology: FISH

Clinical Significance:
These FISH studies identify the genetic alteration characteristic of several major categories of non Hodgkin B cell lymphoma. These include the t(14;18) IGH/BCL2 and BCL6 family of rearrangements identified in follicular lymphomas, the t(11;14) identified in mantle cell lymphoma, and MALT1 gene rearrangements that are identified in a subset of marginal zone B cell lymphomas. The identification of an IGH rearrangement in isolation can also aid in the diagnosis of atypical lymphoid proliferations even when its translocation partner is not elucidated.
