For our clinical studies on CHARGE syndrome we collect information world-wide on growth in order to construct growth curves specifically for the syndrome. For the puberty induction decision tool we perform interviews, both in the Netherlands and at international patient meetings. A new study focussing on early motor development in CHARGE syndrome has recently been started. Children up to 3.5 years of age visiting our CHARGE clinic will be asked to participate.
Our studies on Phelan-McDermid syndrome focus on three aspects. For our longitudinal study on behaviour and development in children we include children up to the age of 18 as long as developmental test results at younger ages are available as well. All individuals with Phelan-McDermid syndrome due to a ring chromosome 22 are welcome to participate in our prospective study on the tumour risk in individuals with a ring chromosome 22. Children who receive an experimental treatment with insulin nose spray via our expert clinic, are enrolled in our evaluation study of this treatment.
Every person with a chromosome 6 aberration world-wide is welcome to participate in our chromosome 6 project. Via a secured website the individual or parent can upload the results of the chromosome studies, after which they receive a personal account. Extensive information, including instruction videos are available at the project's website.
