Description

The E208X variant in the SNAP29 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is predicted to cause loss of normal protein function through protein truncation with a loss of the protein's last 51 amino acids. The E208X variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The E208X variant is a strong candidate for a pathogenic variant, however the possibility it may be a rare benign variant cannot be excluded.
