Genes affected
BRCA1 (HGNC:1100): (BRCA1 DNA repair associated) This gene encodes a 190 kD nuclear phosphoprotein that plays a role in maintaining genomic stability, and it also acts as a tumor suppressor. The BRCA1 gene contains 22 exons spanning about 110 kb of DNA. The encoded protein combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). This gene product associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. This protein thus plays a role in transcription, DNA repair of double-stranded breaks, and recombination. Mutations in this gene are responsible for approximately 40% of inherited breast cancers and more than 80% of inherited breast and ovarian cancers. Alternative splicing plays a role in modulating the subcellular localization and physiological function of this gene. Many alternatively spliced transcript variants, some of which are disease-associated mutations, have been described for this gene, but the full-length natures of only some of these variants has been described. A related pseudogene, which is also located on chromosome 17, has been identified. [provided by RefSeq, May 2020]

The c.3770_3771delAG (p.Glu1257Glyfs*9) variant in the BRCA1 gene is predicted to introduce a premature translation termination codon, which is predicted to result in nonsense-mediated mRNA decay. This variant has been reported in multiple patients with hereditary breast and ovarian cancer (PMID 7606717, 16683254, 17319787, 18627636, 23479189, 27553291). This variant has an extremely low frequency in large databases of genetic variation in the general population. Therefore, the c.3770_3771delAG (p.Glu1257Glyfs*9) variant in the BRCA1 gene is classified as pathogenic. -

A known pathogenic mutation was detected in the BRCA1 gene(p.Glu1257fs).his sequence change creates a premature translational stop signal (p.Glu1257Glyfs*9) in the BRCA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). This variant is present in population databases (rs80357993, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with breast and ovarian cancer (PMID: 16683254, 17319787, 18627636, 23479189, 23683081). This variant is also known as 3890_3891delAG and 3889delAG. ClinVar contains an entry for this variant (Variation ID: 37546). For these reasons, this variant has been classified as Pathogenic. This variant was confirmed by Sanger sequencing. -

The BRCA1 c.3770_3771del (p.Glu1257Glyfs*9) variant alters the translational reading frame of the BRCA1 mRNA and causes the premature termination of BRCA1 protein synthesis. This variant has been reported in the published literature in individuals with breast or ovarian cancer (PMID: 23479189 (2013), 30972954 (2019), 31957001 (2020); BRCA Exchange (http://brcaexchange.org/)). The frequency of this variant in the general population, 0.000087 (1/11484 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. -

The BRCA1 p.Glu1257Glyfs*9 variant was identified in 27 of 18350 proband chromosomes (frequency: 0.0015) from individuals or families with breast or ovarian cancer (Blay 2013, Chen 2009, Cock-Rada 2018, de Juan Jimenez 2013, Heramb 2018, Hirotsu 2014, Konecny 2007, Thirthagiri 2008, van der Hout 2006). The variant was also identified in the following databases: dbSNP (ID: rs80357993) as "With Pathogenic allele", ClinVar (classified as pathogenic by Invitae, Ambry Genetics, GeneDx and fourteen other submitters), COGR, LOVD 3.0 (28x), UMD-LSDB (25x causal), BIC Database (23x with clinical importance), ARUP Laboratories (definitely pathogenic), and in Zhejiang University database (2x). The variant was not identified in Cosmic or MutDB databases. The variant was not identified in the following control databases: the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.3770_3771del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 1257 and leads to a premature stop codon at position 1265. This alteration is then predicted to result in a truncated or absent protein and loss of function. Loss of function variants of the BRCA1 gene are an established mechanism of disease in breast and ovarian cancer and is the type of variant expected to cause the disorder. In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic. -

This variant deletes 2 nucleotides in exon 10 of the BRCA1 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant is also known as 3889delAG and 3888delGA in the literature according to the BIC nomenclature. This variant has been reported in over thirty individuals affected with breast and/or ovarian cancer (PMID: 18627636, 23479189, 23683081, 26026974, 26757417, 26824983, 27553291, 28176296, 28528518, 29339979, 31815095, 33471991, 33842585). This variant has been identified in 2/251226 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRCA1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

The c.3770_3771delAG pathogenic mutation, located in coding exon 9 of the BRCA1 gene, results from a deletion of two nucleotides at nucleotide positions 3770 to 3771, causing a translational frameshift with a predicted alternate stop codon (p.E1257Gfs*9). This mutation has been reported in multiple breast and ovarian cancer families to date (Couch FJ et al. Hum. Mutat., 1996;8:8-18; Liede A et al. Am. J. Hum. Genet., 2002 Sep;71:595-606; Blay P et al.

Ann Transl Med, 2021 Mar;9:364). Of note, this alteration is also designated as 3889delAG 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. -

This variant deletes 2 nucleotides in exon 10 of the BRCA1 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant is also known as 3889delAG and 3888delGA in the literature according to the BIC nomenclature. This variant has been reported in over thirty individuals affected with breast and/or ovarian cancer (PMID: 18627636, 23479189, 23683081, 26026974, 26757417, 26824983, 27553291, 28176296, 28528518, 29339979, 31815095, 33471991, 33842585). This variant has been identified in 2/251226 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRCA1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

The BRCA1 c.3770_3771delAG variant is predicted to result in a frameshift and premature protein termination (p.Glu1257Glyfs*9). This variant has been reported in patients with early onset and familial breast and ovarian cancer (de Juan Jiménez et al. 2013. PubMed ID: 23479189; Gabaldó Barrios. 2017. PubMed ID: 28477318). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD and is reported in the ClinVar database as pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/37546/). Frameshift variants in BRCA1 are expected to be pathogenic. We interpret this variant as pathogenic. -
