Abstract excerpt
BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominant vascular disorder with three disease-causing genes identified to date: ENG, ACVRL1, and SMAD4. We report an HHT patient with allelic dropout that on routine sequence analysis for a known mutation in the family (c.817-3T>G in ENG) initially seemed to be homozygous for the mutation. AIM: To explore the possibility of allelic dropout...
