Pitt Hopkins Syndrome (or PTHS) is a neurodevelopmental disorder. We currently have nearly 1000 families with PTHS in our online groups and family registry, and this number is growing every day as genetic diagnoses increase. Tcf4, the gene that causes Pitt Hopkins is implicated in various other disorders too, including Schizophrenia , Autism, Fuchs Corneal Dystrophy, and Liver Disease. The study of this important gene could have wide reaching effects for Pitt Hopkins and beyond. Even though the cause of PTHS is known, there are currently no pharmaceutical treatments available for this disorder. The Pitt Hopkins Foundation is committed to accelerating progress toward effective treatments and ultimately a cure for PTHS, by directly funding the most promising research.
