Labcorp Genetics (formerly Invitae), Labcorp RCV001931715 SCV002209204 pathogenic Cone-rod dystrophy 13; Leber congenital amaurosis 6 2021-12-22 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Disruption of this splice site has been observed in individual(s) with Leber congenital amaurosis (PMID: 26047050). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs771116776, gnomAD 0.002%). This sequence change affects a donor splice site in intron 22 of the RPGRIP1 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 RPGRIP1 are known to be pathogenic (PMID: 11528500, 23105016).
