Ambry Genetics | RCV001017254 | SCV001178303 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2023-03-30 | criteria provided, single submitter | clinical testing | The c.109-2A>C intronic variant results from an A to C substitution two nucleotides upstream from coding exon 3 in the PALB2 gene. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice acceptor site and will result in the creation or strengthening of a novel splice acceptor site; however, direct evidence is insufficient at this time (Ambry internal data). Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic |
