Etiology of HHT Causes of HHT As already mentioned, it is an autosomal dominant disorder, with 5 genetic types and homozygous condition being incompatible with life. [lecturio.com]

Etiology OWRD (ie, HHT) is a disorder that is inherited in an autosomal dominant fashion, [23, 24] though 20% of patients are unaware of a positive family history, partly because the lesions may be minimal and because 10% of patients have no episodes [emedicine.medscape.com]

However, recent epidemiologic surveys indicate that the disorder is much more frequent than originally thought, possibly due to increased awareness of and interest in this disorder. [ommbid.mhmedical.com]
