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

The map is a work in progress and currently has 348 family locations across the world.

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.
