Ambry Genetics RCV002407934 SCV002723133 uncertain significance Hereditary cancer-predisposing syndrome 2020-03-27 criteria provided, single submitter clinical testing The p.E629G variant (also known as c.1886A>G), located in coding exon 19 of the RB1 gene, results from an A to G substitution at nucleotide position 1886. The glutamic acid at codon 629 is replaced by glycine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003514579 SCV004248562 uncertain significance Retinoblastoma 2023-01-19 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RB1 protein function. ClinVar contains an entry for this variant (Variation ID: 1781979). This variant has not been reported in the literature in individuals affected with RB1-related conditions. 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 629 of the RB1 protein (p.Glu629Gly).
