The ACVRL1 c.905T>C; p.Leu302Pro variant has not been reported in the literature or gene-specific databases. However, a different variant at this codon, p.Leu302Arg, has been reported to segregate with disease in a German family with hereditary hemorrhagic telangiectasia (Schulte 2005). The highly conserved leucine at codon 302 is located in the protein kinase domain, and computational algorithms (SIFT, PolyPhen2, MutationTaster) predict the p.Leu302Pro variant to be damaging to the protein. Due to the limited information regarding p.Leu302Pro, its clinical significance is uncertain at this time. REFERENCES Schulte C et al. High frequency of ENG and ALK1/ACVRL1 mutations in German HHT patients. Hum Mutat. 2005 Jun;25(6):595.
