Description

This sequence change creates a premature translational stop signal (p.Arg1701*) in the CCDC88C gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 328 amino acid(s) of the CCDC88C protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CCDC88C-related conditions. This variant disrupts a region of the CCDC88C protein in which other variant(s) (p.Glu1949Glyfs*26) have been determined to be pathogenic (PMID: 23042809). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
