Description

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ACVRL1 are known to be pathogenic (PMID: 15879500). This variant has not been reported in the literature in individuals with ACVRL1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Cys207*) in the ACVRL1 gene. It is expected to result in an absent or disrupted protein product.
