Invitae | RCV003537308 | SCV000965309 | pathogenic | Familial adenomatous polyposis 1 | 2019-03-13 | criteria provided, single submitter | clinical testing | Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in APC are known to be pathogenic (PMID: 17963004, 20685668). For these reasons, this variant has been classified as Pathogenic. Experimental studies using mRNA extracted from peripheral blood cells of an affected individual have shown that this variant results in aberrant splicing (PMID: 10083733). This variant has been observed in an individual affected with familial adenomatous polyposis (PMID: 10083733). This variant is described as an ag/TT -> cg/TT change at the splice acceptor site of exon5 in the literature. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 5 of the APC gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. |
