Description

This variant changes 1 nucleotide in exon 22 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 reported in an individual who underwent genetic testing (PMID: 28152038). 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.

Description

The p.E2924* pathogenic mutation (also known as c.8770G>T), located in coding exon 21 of the BRCA2 gene, results from a G to T substitution at nucleotide position 8770. This changes the amino acid from a glutamic acid to a stop codon within coding exon 21. 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.
