Ambry Genetics RCV000491509 SCV000579782 likely pathogenic Hereditary cancer-predisposing syndrome 2017-12-23 criteria provided, single submitter clinical testing Lines of evidence used in support of classification: Detected in individual satisfying established diagnostic critera for classic disease without a clear mutation,Rarity in general population databases (dbsnp, esp, 1000 genomes),In silico models in agreement (deleterious) and/or completely conserved position in appropriate species
Invitae RCV000646317 SCV000768085 uncertain significance Familial adenomatous polyposis 1 2017-11-22 criteria provided, single submitter clinical testing This sequence change falls in intron 5 of the APC gene. It does not directly change the encoded amino acid sequence of the APC protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency). This variant has been reported in a family affected with familial adenomatous polyposis (PMID: 9375853) and in an individual suspected with familial adenomatous polyposis (PMID: 23159591). ClinVar contains an entry for this variant (Variation ID: 428099). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
