Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_005732.4(RAD50):c.2983_2986delGAAA(p.Glu995ArgfsTer2) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,613,458 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. E995E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Hereditary cancer-predisposing syndrome Pathogenic:3
This sequence change creates a premature translational stop signal (p.Glu995Argfs*2) 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). This variant is present in population databases (rs587782488, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 128015). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

The c.2983_2986delGAAA pathogenic mutation, located in coding exon 19 of the RAD50 gene, results from a deletion of 4 nucleotides at nucleotide positions 2983 to 2986, causing a translational frameshift with a predicted alternate stop codon (p.E995Rfs*2). This alteration has been previously identified in a Chinese breast cancer cohort (Li JY et al. Int. J. Cancer. 2019 01;144:281-289). Of note, this alteration is also designated as c.2980_2983del in published literature. In addition to the clinical data presented in the literature, 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. -
