| Ambry Genetics | RCV000566174 | SCV000663644 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-03-10 | criteria provided, single submitter | clinical testing | The p.G145A variant (also known as c.434G>C), located in coding exon 4 of the RAD50 gene, results from a G to C substitution at nucleotide position 434. The glycine at codon 145 is replaced by alanine, an amino acid with similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 120000 alleles tested) in our clinical cohort. This amino acid position is highly 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. |
| Invitae | RCV000566174 | SCV000753297 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-09-10 | 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 expected to disrupt RAD50 protein function. ClinVar contains an entry for this variant (Variation ID: 480408). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 145 of the RAD50 protein (p.Gly145Ala). |
