Description

The p.E1415* pathogenic mutation (also known as c.4243G>T), located in coding exon 10 of the BRCA2 gene, results from a G to T substitution at nucleotide position 4243. This changes the amino acid from a glutamic acid to a stop codon within coding exon 10. This alteration has been previously reported in individuals diagnosed with ovarian cancer (Walsh T et al. Proc. Natl. Acad. Sci. U.S.A. 2011 Nov;108:18032-7; Carter NJ et al. Gynecol. Oncol., 2018 12;151:481-488) and in an individual diagnosed with a head and neck squamous cell cancer (Chandrasekharappa SC et al. Cancer, 2017 Oct;123:3943-3954). This alteration was also identified in a large, worldwide study of BRCA1/2 mutation positive families (Rebbeck TR et al. Hum. Mutat., 2018 05;39:593-620). Of note, this alteration is also designated as "4471G>T" in published literature. 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.

Description

This variant changes 1 nucleotide in exon 11 of the BRCA2 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been observed in multiple individuals affected with breast, ovarian and fallopian tube cancer (PMID: 22006311, 30322717, 33471991; Leiden Open Variation Database DB-ID BRCA2_002639; Color internal data). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of BRCA2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.
