RCV002527174 | SCV003439188 | pathogenic | Familial adenomatous polyposis 1 | 2022-01-03 | criteria provided, single submitter | clinical testing | This variant is expected to disrupt the EB1 and HDLG binding sites, which mediate interactions with the cytoskeleton (PMID: 15311282, 17293347). While functional studies have not been performed to directly test the effect on APC protein function, this suggests that disruption of the C-terminal portion of the protein is functionally important. For these reasons, this variant has been classified as Pathogenic. A different truncation (p.Tyr2645Lysfs*14) that lies downstream of this variant has been determined to be pathogenic (PMID: 9824584, 1316610, 27081525, 8381579, 22135120, Invitae). This suggests that deletion of this region of the APC protein is causative of disease. This premature translational stop signal has been observed in individual(s) with familial adenomatous polyposis (PMID: 10077047). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln1237Glufs*2) in the APC gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 1607 amino acid(s) of the APC protein. |
