Labcorp Genetics (formerly Invitae), Labcorp RCV001971319 SCV002258875 likely pathogenic Carpenter syndrome 2021-03-19 criteria provided, single submitter clinical testing This variant results in the deletion of part of exon 4 (c.358_398+177delinsGGTGTACAGTTG) of the RAB23 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 RAB23 are known to be pathogenic (PMID: 17503333, 21412941). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with RAB23-related conditions. 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. 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.
