Description
The c.1813dup (p.Ile605Asnfs*11) variant in the BRCA2 gene has been detected in multiple patients with breast and/or ovarian cancer [referred as 2034insA and 2041insA in PMID 9150150, 21324516, 22535016] and prostate cancer [PMID 21952622].This variant has been reported in four individuals from the ExAC database (http://exac.broadinstitute.org/variant/22-29091226-TA-T). This one bp duplication in exon 10 results in a frameshift and the creation of a premature stop codon. This variant is expected to result in a loss of function of the protein. It is thus classified as pathogenic.

Description
This variant inserts 1 nucleotide in exon 10 of the BRCA2 gene, creating a frameshift and premature translation stop signal. This variant is also known as 2034insA, 2040insA, 2041insA, 2041dupA, 2041_2042insA, c.1813insA and c.1806dupA in the literature. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in a breast cancer case-control meta-analysis in 20 cases and 1 unaffected control, which is estimated to have an odds ratio for pathogenicity of OR=17.689 (95%CI 2.374 to 131.809; p-value<0.001) (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_001802) and also has been reported in individuals affected with breast, ovarian, pancreatic, prostate and neuroendocrine cancers (PMID: 9150150, 9667259, 18042939, 20104584, 21324516, 21952622, 22729890, 25072261, 28724667, 29433453) and suspected hereditary breast and ovarian cancer families (PMID: 11802209, 21232165, 24156927). In one family, this variant was reported in 11 women affected with breast cancer across three generations (PMID: 9150150). This variant also has been detected in two compound heterozygous individuals with a second pathogenic BRCA2 mutation who exhibited clinical features consistent with Fanconi anemia (PMID: 15070707, 21548014). Haplotype analysis suggests that this variant may be a founder mutation and is common in people of German ancestry (PMID: 9585613, 23199084). This variant has been identified in 3/232106 chromosomes 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.
