Labcorp Genetics (formerly Invitae), Labcorp RCV003109691 SCV003791684 likely pathogenic Cone-rod dystrophy 13; Leber congenital amaurosis 6 2022-05-10 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exon(s) 24 of the RPGRIP1 gene, which includes the termination codon. This deletion extends beyond the assayed region for this gene and therefore may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product. This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. This variant disrupts the C-terminus of the RPGRIP1 protein. Other variant(s) that disrupt this region (p.Val1265Glyfs*19) have been observed in individuals with RPGRIP1-related conditions (PMID: 25412400, 30072743). This suggests that this may be a clinically significant region of the protein. 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.
