Description

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the SACS protein in which other variant(s) (p.Tyr4538*) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with SACS-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Glu2419*) in the SACS gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 2161 amino acid(s) of the SACS protein.
