Invitae RCV001377781 SCV001575204 likely pathogenic Retinitis pigmentosa 12; Leber congenital amaurosis 8 2020-03-04 criteria provided, single submitter clinical testing This sequence change falls in intron 2 of the CRB1 gene. It does not directly change the encoded amino acid sequence of the CRB1 protein, but it affects nucleotides within the consensus splice site of the intron. 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. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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 individual(s) with early onset retinal dystrophy (PMID: 25323024). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency).
