Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_005732.4(RAD50):c.418A>G(p.Met140Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,712 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M140K) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 12, 2022 | The p.M140V variant (also known as c.418A>G), located in coding exon 4 of the RAD50 gene, results from an A to G substitution at nucleotide position 418. The methionine at codon 140 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 07, 2021 | In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RAD50-related disease. This sequence change replaces methionine with valine at codon 140 of the RAD50 protein (p.Met140Val). The methionine residue is moderately conserved and there is a small physicochemical difference between methionine and valine. - |
