Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2
The NM_005732.4(RAD50):c.916G>T(p.Asp306Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,894 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. D306G) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
The p.D306Y variant (also known as c.916G>T), located in coding exon 7 of the RAD50 gene, results from a G to T substitution at nucleotide position 916. The aspartic acid at codon 306 is replaced by tyrosine, an amino acid with highly dissimilar 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.
This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 306 of the RAD50 protein (p.Asp306Tyr). This variant is not present in population databases (gnomAD no frequency). 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: 527371). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
