This sequence change affects an acceptor splice site in intron 8 of the ASCC1 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 ASCC1 are known to be pathogenic (PMID: 30327447). This variant is present in population databases (rs767094468, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with ASCC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1931274). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.

HelpRecord 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.
