Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with ASS1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Tyr207*) in the ASS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ASS1 are known to be pathogenic (PMID: 18473344, 19006241).
