MYB Deletion

Catalogue Numbers
LPH 016-S (5 tests)
LPH 016 (10 tests)

Deletions of chromosome 6q are found in B-CLL, with breakpoints being reported in bands 6q13, q15 and q21.

The MYB gene (Avian Myeloblastosis Viral Oncogene Homolog) is a homologue of the avian v-myb oncogene and has been shown to be highly expressed in all immature lymphoid and myeloid T-cells, but becomes down regulated in mature T or B-cells1.

The MYB gene is located in band 6q23.3 and is provided as a marker for 6q deletion as it is distal to reported deletion breakpoints (6q13, 6q15 and 6q21).

I first came across Cytocell FISH probes in a previous lab I worked in and I was struck by the quality of the products. Since this time, I have been recommending and introducing Cytocell probes across all application areas — now they are the primary FISH probes used in our lab. They have an excellent range of products and their ready-to-use reagent format saves considerable time. As a matter of fact, at a recent conference there was a discussion about the lack of commercial probes for a particular disorder and I was happy to point the participants in the direction of the Cytocell catalogue, which contains the exact probes required. Elizabeth Benner, Medical Technologist at the University of Arizona Health Network
