- BCL6, 3q27.3, Green
The BCL6 product consists of a 165kb probe, labelled in red, centromeric to the BCL6 gene and a green probe, covering a 170kb region telomeric to the BCL6 gene.
Rearrangements of the BCL6 gene have been observed in 28.6-35.5% of Diffuse Large B-Cell Lymphoma (DLBCL) and in 6.4-14.3% of Follicular Lymphoma (FL)1.
This translocation results in the dysregulation of BCL6 and may involve the IGH, IGK and IGL genes, although other non-Ig partner genes have also been identified2,3. BCL6 encodes a 95kD nuclear phosphoprotein belonging to the pox virus zinc finger (POZ)/zinc finger (ZF) family of transcription factors4. BCL6 functions as a transcriptional repressor and plays an important regulatory role in lymphoid cell development and function. In the B-cell lineage, the BCL6 protein is expressed only in germinal centre B cells5. Translocations involving band 3q27.3 affect a 4kb major breakpoint region of BCL6 in the first non-coding exon and 5' region of the first intron, and are common in diffuse large B-cell lymphomas. Recently, an alternative breakpoint cluster region located between 245 and 285kb 5' of BCL6 was identified in Non-Hodgkin Lymphoma (NHL) and may be preferentially associated with follicular lymphoma6.
I am grateful for the excellent products I receive from Cytocell at a reasonable price, but more importantly the superb customer support. The speed in which I receive answers or suggestions makes my life as a director much easier and allows me to focus on patient care. The quality and consistency of Cytocell’s probes means I can trust the results, and my clients get their results in a timely manner. Dr. Theresa C. Brown, Director, Cytogenetics Laboratory, Hayward Genetics Center, Tulane University School of Medicine
