Marjolijn Ligtenberg

Marjolijn Ligtenberg 2018Marjolijn Ligtenberg is head of the Oncogenetics team. This team is specialized in:

  • the detection of constitutive mutations leading to genetic susceptibility to cancer
  • the detection of leukemia specific genetic alterations

Mutations and alterations found can be used as diagnostic, prognostic and predictive markers.

The Oncogenetics team works in close collaboration with the department of Pathology (in the Laboratory Tumor Genetics) and because of this also diagnostic analyses of acquired genetic alterations in solid tumors are performed.


The Oncogenetics team exists of:

  • 4 clinical laboratory geneticists
  • 1 geneticist
  • 16 laboratory technicians

The diagnostic analyses of genetic alterations in solid tumors, is performed by 2 clinical molecular biologists and 9 laboratory technicians of the Laboratory of Tumor Genetics.
