UMCG Centre of Expertise for rare neurodevelopmental disorders.
UNIEK is a centre of expertise for rare disorders in the field of developmental delay, with specific expertise of CHARGE syndrome, Phelan-McDermid syndrome and rare chromosome disorders (in particular of chromosome 6).

We develop and update our expertise constantly by active follow-up of as many patients with these rare disorders as possible, and by conducting scientific research and by providing education.

UNIEK aims to:

  • offer an efficient diagnostic procedure with a minimal burden to the families involved;
  • gain more knowledge about rare genetic causes for developmental delay;
  • improve treatment and support for patients and their families based on outcomes of clinical scientific research and by establishing national and international guidelines.
