Molecular mechanism of this disorder are complex and still no fully dilucidated. The genes mutated in HHT encode endothelial cell-expressed proteins that mediate signalling by the transforming growth factor (TGF)b superfamily. Endoglin (HHT type I) and ACVRL-1 (HHT type 2) mutations are responsible in more than 80% of the individuals. Mutation of SMAD 4 protein (MADH4)cause HHT in association with juvenile polyposis.
