Neurodevelopmental disorders

Group Oegema-Neurodevelopmental disorders


The recently established group led by Renske Oegema focuses on neurodevelopmental disorders, especially brain malformations, epilepsy and the role of epigenetic mechanisms in the brain.

Group members:

  • Renske Oegema, MD, PhD, principal investigator, assistant professor, clinical geneticist
  • Amber van Oirsouw, PhD student. Project: KDM2B and the epigenetic machinery
  • Richard van Jaarsveld, post-doc. Co-promotor on the project: KDM2B and the epigenetic machinery

Renske Oegema is an internationally recognized expert regarding congenital brain malformations. Her focus is on malformations of the brain cortex, a.k.a. malformations of cortical development (MCD), for example heterotopia, polymicrogyria and lissencephaly.To accelerate research collaborations, and to share and disseminate knowledge she co-founded and was co-leader of the European network for brain malformations Neuro-MIG (2016-2021).

The group has, through international collaboration, delineated a novel neurodevelopmental syndrome cause by mutations in the KDM2B gene (Van Jaarsveld et al, submitted). KDM2B is an epigenetic regulator and we have established an distinct KDM2B episignature, in collaboration with Marielle Alders (Amsterdam UMC) and Bekim Sadikovic (London, Canada). We aim to expand the patient cohort to study the clinical features associated with this syndrome. In parallel we are developing an in vitro neuronal cell model to study the effect of KDM2B mutations.

In the future, we aim to expand our study to our epigenetic disorders affecting neurodevelopment.
