RESUMO
OBJECTIVE: To identify the mutation of ENG and ALK1 genes in a hereditary hemorrhagic telangiectasia pedigree. METHODS: 14 exons of ENG gene and 9 exons of ALK1 gene in 11 menbers of this pedigree 4 generation were amplified by reverse transcription-polymerase chain reaction (RT-PCR), the PCR products were screened by direct sequencing. RESULTS: A nonsense mutation c.447G > A was found in exon 4 of ENG gen of the pedigreee, resulting in change of Trp 149 into Stop, while no gene mutation was found in ALK1 gene. CONCLUSION: The hereditary hemorrhagic telangiectasia in this pedigree is caused by the nonsense mutation c.447G > A in ENG gene.
