Labcorp Genetics (formerly Invitae), Labcorp RCV003628415 SCV004504238 uncertain significance Retinoblastoma 2023-03-07 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt 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. This variant has been observed in individual(s) with retinoblastoma (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 14 of the RB1 gene. It does not directly change the encoded amino acid sequence of the RB1 protein. It affects a nucleotide within the consensus splice site.
