ClinVar
Submissions by phenotype
Hereditary cancer-predisposing syndrome Pathogenic:2
For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 240219). 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 0.003%). This sequence change creates a premature translational stop signal (p.Arg656*) in the RAD50 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RAD50 are known to be pathogenic (PMID: 19409520). -
The p.R656* pathogenic mutation (also known as c.1966C>T), located in coding exon 12 of the RAD50 gene, results from a C to T substitution at nucleotide position 1966. This changes the amino acid from an arginine to a stop codon within coding exon 12. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
Nijmegen breakage syndrome-like disorder Pathogenic:2

not provided Pathogenic:1
The RAD50 c.1966C>T (p.Arg656*) variant causes the premature termination of RAD50 protein synthesis. This variant has been reported in the published literature in an individual with breast cancer (PMID: 33313162 (2020)). The frequency of this variant in the general population, 0.000008 (2/250726 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. -
