The PTEN Hamartoma Tumor Syndrome Foundation was founded to find treatments or therapies for PTEN Syndromes. Our team is developing research tools to complement existing research, including our IRB-approved patient registry and biorepository. We fund research, provide PHTS education, and supporting patients. PHTS includes Cowden syndrome (CS), Bannayan-Riley-Ruvalcaba syndrome (BRRS), PTEN-related Proteus syndrome (PS), and Proteus-like syndrome.

We are a patient run organization founded in Dec 2013 to serve the PHTS community by connecting patients and clinicians to collaborate and work together toward a treatment or cure.
