Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000059.4(BRCA2):c.5789T>A(p.Leu1930Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. 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 Pathogenic (★★★). Synonymous variant affecting the same amino acid position (i.e. L1930L) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 07, 2019 | The p.L1930* pathogenic mutation (also known as c.5789T>A), located in coding exon 10 of the BRCA2 gene, results from a T to A substitution at nucleotide position 5789. This changes the amino acid from a leucine to a stop codon within coding exon 10. This alteration was identified in a large, worldwide study of BRCA1/2 mutation positive families (Rebbeck TR et al. Hum. Mutat. 2018 05;39:593-620). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
