GeneDx RCV000202100 SCV000279573 pathogenic not provided 2018-11-08 criteria provided, single submitter clinical testing This deletion of 2 nucleotides in APC is denoted c.4393_4394delAG at the cDNA level and p.Ser1465TrpfsX3 (S1465WfsX3) at the protein level. The normal sequence, with the bases that are deleted in brackets, is AGAG[delAG]TGGA. The deletion causes a frameshift which changes a Serine to a Tryptophan at codon 1465, and creates a premature stop codon at position 3 of the new reading frame. This variant is predicted to cause loss of normal protein function through protein truncation. APC c.4393_4394delAG has been observed in many families with Familial Adenomatous Polyposis (Miyoshi 1992, Dobbie 1996, Enomoto 2000, Aceto 2005, Friedl 2005, Castellsagu? 2010, Schafer 2016, Neffa 2018). We consider this variant to be pathogenic.

Invitae RCV000646370 SCV000768139 pathogenic Familial adenomatous polyposis 1 2018-10-13 criteria provided, single submitter clinical testing This sequence change results in a premature translational stop signal in the APC gene (p.Ser1465Trpfs*3). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 1379 amino acids of the APC protein. This variant is not present in population databases (ExAC no frequency). This variant has been reported in many individuals affected with APC-related disease, including familial adenomatous polyposis and Gardner syndrome (PMID: 1316610, 10768871, 20685668, 28782241, 28018803, 26840078). This variant is also known as a 2-bp deletion (AG) at codon 1465, 4292-4293delGA and AG del in the literature. ClinVar contains an entry for this variant (Variation ID: 811). A different truncation (p.Asn1979Thrfs*64) that lies downstream of this variant has been determined to be pathogenic (PMID: 9824584, 20434453, 26681312). This suggests that deletion of this region of the APC protein is causative of disease. For these reasons, this variant has been classified as Pathogenic.
