Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.
The NM_005732.4(RAD50):c.130A>T(p.Thr44Ser) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000937 in 1,600,622 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. 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. T44I) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 15, 2024 | This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 44 of the RAD50 protein (p.Thr44Ser). This variant is present in population databases (rs377388354, gnomAD 0.006%). 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: 232646). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 29, 2023 | The p.T44S variant (also known as c.130A>T), located in coding exon 2 of the RAD50 gene, results from a A to T substitution at nucleotide position 130. This variant impacts the first base pair of coding exon 2. The threonine at codon 44 is replaced by serine, an amino acid with similar properties. 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. - |
