In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 265552). Disruption of this splice site has been observed in individual(s) with breast cancer (PMID: 28825143, 32068069, 32339256, 33193564). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 10 of the PALB2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PALB2 are known to be pathogenic (PMID: 17200668, 17200671, 17200672, 24136930, 25099575).

The c.3114-1G>A intronic variant results from a G to A substitution one nucleotide upstream from coding exon 11 of the PALB2 gene. This alteration has been detected in multiple Chinese breast cancer patients (Zhang K et al. Breast Cancer Res Treat, 2017 Dec;166:865-873; Deng M et al. Int J Cancer, 2019 09;145:1517-1528; Zhou J et al. Cancer, 2020 07;126:3202-3208; Kwong A et al. J Mol Diagn, 2020 04;22:544-554; Hu ZY et al. Front Genet, 2020 Aug;11:829). 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. 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. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
