This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in ATP7B are known to be pathogenic (PMID: 10441329, 16283883). 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. Disruption of this splice site has been observed in individual(s) with Wilson disease (PMID: 18483695). This sequence change affects an acceptor splice site in intron 18 of the ATP7B gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.

Record last updated Sep 29, 2024
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.
