The Kleefstra World Map

Connecting the Community

The Kleefstra Worldwide Map demonstrates the connectedness of our community and enables opportunities for engagement with each other and the research community.Our ability to not only recognize our current population of individuals with Kleefstra syndrome, but to also showcase the growth of our community over time, makes Kleefstra syndrome a more attractive rare disease to build programs around as we march towards a treatment!

I Love Someone Rare

We’re kind of a big deal. Everyone in the KS community loves someone rare, but odds are, everyone else in the world does, too. 1 in 25,000 are expected to have Kleefstra syndrome. Every day, 10 people around the world will be born with Kleefstra syndrome. We invite you to join in this effort supported by our international network of families and organizations!
