Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_000059.4(BRCA2):āc.8879A>Gā(p.Gln2960Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,254 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q2960K) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 01, 2017 | This variant is present in population databases (rs757088844, ExAC 0.002%) but has not been reported in the literature in individuals with a BRCA2-related disease. This sequence change replaces glutamine with arginine at codon 2960 of the BRCA2 protein (p.Gln2960Arg). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and arginine. 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, but these predictions have not been confirmed by published functional studies. In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. - |
