Proteus Syndrome Foundation

Welcome to the Proteus Syndrome Foundation (PSF). We’re a community of families, caregivers, clinicians, and researchers united by a single purpose: ensuring no one faces Proteus syndrome alone. Our work brings people together, drives progress, and provides real support at every stage of the journey.

Through our family conferences, our PSF camp retreat, and medical assistance programs, we create spaces where families can connect, learn, and lean on one another. Proteus syndrome can feel overwhelming and isolating — but with the PSF behind you, you will always have a place to turn, people who understand, and a network committed to moving care and research forward.

You’re welcome here. Let’s move forward together.

Wheels for Jeffrey

Recently Jeffrey's power wheelchair failed him. ​The brakes on his wheelchair stopped working, causing an accident that resulted in a trip to the hospital. Thankfully, Jeffrey was not seriously injured, but the incident highlighted a reality he faces every day: his current wheelchair is no longer safe or reliable.

About the Proteus Syndrome

Proteus syndrome is a rare disorder characterized by overgrowth of various tissues of the body. The cause of the disorder is a mosaic variant in a gene called AKT1. Disproportionate, asymmetric overgrowth occurs in a mosaic pattern (i.e., a random “patchy” pattern of affected and unaffected areas).

Who We Are

Welcome to the Proteus Syndrome Foundation (PSF). We are composed of families who connect with each other through the foundation and professionals who work tirelessly to help find effective treatments for Proteus. The PSF provides support through family conferences, family sharing through our (new) PSF Forum on our web page, and grants for families in need of assistance. Proteus syndrome can be an isolating syndrome, but as we come together under the PSF umbrella, we will never stand alone.
