Welcome to the Costello syndrome interactive  map of the world. Our interactive map illustrates families affected by Costello syndrome across the globe.

Please note that, for privacy reasons, the map is at town- or zip code-level, not at the house level. This means that each family is represented by a  dot at the city level  rather than the home address.

If you have a Costello syndrome person within your family  and would like to be included on the map, please fill out our membership form.
