Probe Specification

  • PDGFRB, 5q32, Red
  • PDGFRB, 5q32, Green

The PDGFRB product consists of a 107kb probe, labelled in red, located centromeric to the PDGFRB gene, including the D5S2618 and D5S2619 markers and a green probe, covering a 154kb region telomeric to the PDGFRB gene, including the D5S2015 marker.

Probe Information

Some cases of Chronic Myelomonocytic Leukaemia (CMML) have constitutive activation of the gene for PDGFRB (platelet derived growth factor receptor beta) which encodes a receptor tyrosine kinase1.

The activation is usually caused by a t(5;12)(q32;p13) translocation which results in the ETV6 (TEL)-PDGFRB fusion gene. Patients with this fusion have reportedly been shown to be responsive to the drug imatinib mesylate (Gleevec)1, which specifically inhibits the kinase activity of PDGFRB. The breakpoint in PDGFRB is characteristically located in intron 102,3.

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
