GeneDx RCV001797261 SCV002038683 likely pathogenic not provided 2022-02-11 criteria provided, single submitter clinical testing Canonical splice site variant predicted to result in a null allele in a gene for which loss-of-function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV002541305 SCV002983333 likely pathogenic Imerslund-Grasbeck syndrome 2022-02-01 criteria provided, single submitter clinical testing 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: 1328629). This variant has not been reported in the literature in individuals affected with CUBN-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 29 of the CUBN 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 CUBN are known to be pathogenic (PMID: 15024727, 22929189).
