Ambry Genetics RCV001024323 SCV001186315 likely benign Hereditary cancer-predisposing syndrome 2022-12-21 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
Invitae RCV001246900 SCV001420292 uncertain significance Retinoblastoma 2024-01-28 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 187 of the RB1 protein (p.Ser187Phe). This variant is present in population databases (rs770277291, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with RB1-related conditions. ClinVar contains an entry for this variant (Variation ID: 825848). 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 with a negative predictive value of 80%. 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.
Color Diagnostics, LLC DBA Color Health RCV001246900 SCV004357196 uncertain significance Retinoblastoma 2023-01-18 criteria provided, single submitter clinical testing This missense variant replaces serine with phenylalanine at codon 187 of the RB1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 2/248866 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
All of Us Research Program, National Institutes of Health RCV001246900 SCV004844615 uncertain significance Retinoblastoma 2023-12-01 criteria provided, single submitter clinical testing This missense variant replaces serine with phenylalanine at codon 187 of the RB1 protein.
