Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 8P and 1B. PM1PM2PP3_StrongBP6
The NM_000059.4(BRCA2):c.3655T>C(p.Phe1219Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 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. F1219S) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Likely benign, criteria provided, single submitter | curation | University of Washington Department of Laboratory Medicine, University of Washington | Mar 23, 2023 | Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673). - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 10, 2022 | The p.F1219L variant (also known as c.3655T>C), located in coding exon 10 of the BRCA2 gene, results from a T to C substitution at nucleotide position 3655. The phenylalanine at codon 1219 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |

Hereditary breast ovarian cancer syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 12, 2022 | ClinVar contains an entry for this variant (Variation ID: 51500). 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. Experimental studies have shown that this missense change affects BRCA2 function (PMID: 19747923). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRCA2 protein function. This missense change has been observed in individual(s) with clinical features of BRCA2-related conditions (PMID: 10923033). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1219 of the BRCA2 protein (p.Phe1219Leu). - |
