This variant results from an in-frame CCTCCC deletion at nucleotide positions 794 to 799. This results in the deletion of three residues (threonine, serine and arginine) and substitutes a single serine between codons 265 and 267. These amino acid positions are well conserved in available vertebrate species. In our cohort, this variant was identified in multiple individuals with hereditary hemorrhagic telangiectasia (HHT) in one family and was shown to segregate with disease (Ambry internal data).
