## Abstract Juvenile polyposis (JP) and hereditary hemorrhagic telangiectasia (HHT) are clinically distinct diseases caused by mutations in __SMAD4__ and __BMPR1A__ (for JP) and __endoglin__ and __ALK1__ (for HHT). Recently, a combined syndrome of JPβHHT was described that is also caused by mutatio
