Labcorp Genetics (formerly Invitae), Labcorp RCV003062583 SCV003442130 uncertain significance Retinoblastoma 2022-06-08 criteria provided, single submitter clinical testing This variant is also known as g.61806A>G. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This missense change has been observed in individual(s) with retinoblastoma (PMID: 14722923). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 313 of the RB1 protein (p.Glu313Gly).
