Description

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the PRF1 protein in which other variant(s) (p.Asp491Asn) have been determined to be pathogenic (PMID: 17477373, 25577959, 33746956). 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 PRF1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.His286Glnfs*3) in the PRF1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 270 amino acid(s) of the PRF1 protein.
