PDGFRB Breakapart

Catalogue Numbers
LPH 031 (10 tests)
LPH 031-S (5 tests)

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.
