Labcorp Genetics (formerly Invitae), Labcorp RCV001236081 SCV001408793 likely pathogenic Cone-rod dystrophy 13; Leber congenital amaurosis 6 2019-09-10 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. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in RPGRIP1 are known to be pathogenic (PMID: 11528500, 23105016). 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. This variant has been observed in an individual with clinical features of Leber congenital amaurosis (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 2 of the RPGRIP1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
