Invitae | RCV000474620 | SCV000552497 | pathogenic | Familial adenomatous polyposis 1 | 2018-08-16 | criteria provided, single submitter | clinical testing | This sequence change deletes 4 nucleotides from exon 16 of the APC mRNA (c.4391_4394delAGAG), causing a frameshift at codon 1464. This creates a premature translational stop signal in the last exon of the APC mRNA (p.Glu1464Valfs*8). While this is not anticipated to result in nonsense mediated decay, it is expected to result in a truncated APC protein. Loss-of-function variants in APC are known to be pathogenic. This particular variant has been reported in the literature in individuals affected with familial adenomatous polyposis (FAP) (PMID: 20685668, 15108286, 16088911, 21643010, 20223039, 23159591). In one individual, this variant was reported to arise as a de novo sequence change (PMID: 15108286). In addition, multiple pathogenic loss-of-function variants have been identified downstream of this sequence change in exon 16 of the APC gene.  ClinVar contains an entry for this variant (Variation ID: 812). For these reasons, this variant has been classified as Pathogenic. |
