What genes are known to cause HHT? There are four genes that are known to be associated with HHT. The first two, ENG and ACVRL1 (ALK1) lead to classical HHT. The third gene SMAD4 causes juvenile polyps to develop in the colon as well as symptoms of HHT. Pathogenic (harmful) genetic changes in the GDF2 … Read morehttps://www.med.unc.edu/hhtcenter/wp-content/uploads/sites/672/2022/03/dna-strand.jpg
