PURPOSE: Determine the variant detection rate for ENG, ACVRL1, and SMAD4 in individuals who meet consensus (Curaçao) criteria for the clinical diagnosis of hereditary hemorrhagic telangiectasia. METHODS: Review of HHT center database for individuals with three or more HHT diagnostic criteria, in whom molecular genetic analysis for ENG, ACVRL1, and SMAD4 had been performed. RESULTS: A variant known or suspected to be causal was detected in ENG in 67/152 (44.1%; 95% confidence interval [CI], 36.0-52.4%), ACVRL1 in 79/152 (52.0%; 95% CI, 43.7-60.1%), and SMAD4 in 2/152 (1.3%; 95% CI, 0.2-4.7%) family probands with definite HHT. Only 4/152 (2.6%; 95% CI, 0.7-6.6%) family probands did not have a variant in one of these genes. CONCLUSION: Previous reports of the variant detection rate for ENG and ACVRL1 in HHT patients have come from laboratories, which receive samples from clinicians with a wide range of expertise in recognizing clinical manifestations of HHT. These studies suggest a significantly lower detection rate (~75-85%) than we have found in patients who meet strictly applied consensus criteria (96.1%). Analysis of SMAD4 adds an additional detection rate of 1.3%. HHT as defined by the Curaçao criteria is highly predictive of a causative variant in either ENG or ACVRL1.
