Other genes mutated in MPN

Recent studies have found several genes mutated in MPNs, with low to medium frequency. These mutated genes are not specific for MPNs, and their importance in the diagnosis and prognostic evaluation of MPNs has yet to be determined. However mutations in these genes found with significant frequency in MPNs can be sequenced to affirm the clonality of a disorder.
The most common mutations are presented below, followed by a list of laboratories that offer screening for these mutations.

• TET2

  TET2 has been found mutated in various myeloid disorders with frequencies varying from 5 to 20% depending on the MPN subtype.

• ASXL1

  This gene plays a role in the epigenetic regulation. ASXL1

• EZH2

  This gene plays a role in the epigenetic regulation. EZH2

• CBL1

  CBL encodes for an ubiquitin ligase able to target cytokine receptors for proteasome degradation. Its mutation has been described in MPN and mixed MDS-MPN. CBL1
