Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP6
The NM_000059.4(BRCA2):c.5927G>A(p.Gly1976Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,696 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G1976R) has been classified as Likely benign.

Hereditary breast ovarian cancer syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 17, 2020 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with BRCA2-related conditions. This variant is present in population databases (rs587782751, ExAC 0.006%). This sequence change replaces glycine with glutamic acid at codon 1976 of the BRCA2 protein (p.Gly1976Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. - |
