The ENG c.704_709delCGGTGA; p.Thr235_Val236del variant, to our knowledge, is not reported in the medical literature or gene specific databases. This variant is also absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. This variant deletes a threonine and valine residue leaving the rest of the protein in-frame. A different in-frame deletion of the valine 236 codon (c.706_708delGTG; p.Val236del) is reported in the literature in an individual with HHT (Brakensiek 2008). However, due to limited information, the clinical significance of the p.Thr235_Val236del variant is uncertain at this time. REFERENCES Brakensiek K et al. Detection of a significant association between mutations in the ACVRL1 gene and hepatic involvement in German patients with hereditary haemorrhagic telangiectasia. Clin Genet. 2008 Aug;74(2):171-7.
