MECP2 Duplication Syndrome

MECP2 gene duplication syndrome is a rare and severe genetic disorder. The syndrome is mainly characterized by intellectual disability, hypotonia, lack of speech and seizures. The symptoms and their intensity vary from child to child.

Since its discovery in 2005, the syndrome has attracted the interest of several research groups. Find details about projects, publications and the experts’ webinars.

Our association is aiming to raise awareness on rare diseases, identify projects and participate in their funding and support and inform families to enhance quality of live for children with MECP2 duplication syndrome.

Support and donate

Contribute to projects to advance research, support families, improve care, or help the development of our association. 

Clinical research needs all patients with MECP2 duplication syndrome in order to gather as much information as possible about this rare disease. There are several registries where people with MECP2 duplication syndrome can be registered to increase knowledge about MECP2 and to advance drug research.
