Limitations
Laboratory test results should always be considered in the context of clinical observations. This test was developed and its performance characteristics determined by med fusion. It has not been cleared or approved by the U.S. Food and Drug Administration
(FDA). The FDA has determined that such clearance or approval is not necessary. This test is used for clinical purposes. It should not be regarded as investigational for research. This laboratory is certified under the Clinical Laboratory Improvement Amendments
of 1988 (CLIA) as qualified to perform high complexity clinical laboratory testing.

Clinical Significance
BCL6 gene rearrangements are frequently found in B cell non-Hodgkin Lymphoma (B-NHL) due to the translocations involving the BCL6 gene locus. These translocations result in deregulation of BCL6 gene and may involve immunoglobulin gene loci such as IGH, IGK and IGL. BCL6 gene rearranging translocations are seen in 15-40% of Diffuse Large B-Cell Lymphomas (DLBCL) and 6-15% of Follicular Lymphomas (FL).
