ABSTRACT
Objective:
To study the mutation of ENG, ACVRL1, and SMAD4 genes in one of a family of hereditary hemorrhagic telangiectasia (HHT) and explore its molecular pathogenesis.Methods:
A family spectrum of a patient with a clinical diagnosis of HHT was surveyed. Peripheral blood samples from proband and their eldest were collected, and ENG, ACVRL1 and SMAD4 gene analysis was performed by chip capture high-throughput sequencing. The mutation detected was verified by Sanger.Results:
9 of the 71 family members were diagnosed with HHT with the main manifestation of recurrent nasal bleeding. Genetic analysis showed that the proband and the eldest son of ENG gene exon 9 frameshift mutation c.1502-1503insGG (p.Gly501GlyfsX18) , and mutations in ACVRL1 and SMAD4 genes were not detected.Conclusion:
The frameshift mutation c.1502-1503insGG (p.Gly501GlyfsX18) of the ENG gene is the genetic basis for the pathogenesis of this HHT family.
