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]

Pathogenic, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The p.Arg1203X variant has been previously reported in the literature in 7 of 12470 individuals with hereditary breast or ovarian cancer (Selected publications: Konstantopoulou 2008, Manguoglu 2003, Borg 2010, Kim 2012). The variant was also reported 22 times in the UMD database ase "causal" and 31 times in the BIC database as "clinically important". The variant was also reported 1 time in the ESP project at low frequency (0.0002) and by dbSNP (ID: rs62625308). This variant leads to a premature stop codon at position 1203, which is predicted to lead to a truncated or absent protein and loss of function. Loss of function variants of the BRCA1 gene are an established mechanism of disease for hereditary breast and ovarian cancer. In summary, based on the above information, this variant is classified as pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 24, 2019The p.Arg1203X variant in BRCA1 has been reported in >40 individuals with BRCA1-associated cancers (Friedman 1994, Manguoglu 2003, Walsh 2011, Solano 2012, Kim 2012, Juwle 2012, Couch 2015, Breast Cancer Information Core (BIC) database, Sharing Clinical Reports Project). This variant has been identified in 1/17194 East Asian and 2/111402 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs62625308). This nonsense variant leads to a premature termination codon at position 1203, which is predicted to lead to a truncated or absent protein. Heterozygous loss of function of the BRCA1 gene is an established disease mechanism in individuals with hereditary breast and ovarian cancer (HBOC). In addition, this variant was classified as Pathogenic on April 22, 2016 by the ClinGen-approved ENIGMA expert panel (ClinVar SCV000282311.1). In summary, this variant meets criteria to be classified as pathogenic for HBOC in an autosomal dominant manner. ACMG/AMP Criteria applied: PVS1, PM2, PS4. -

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpAug 13, 2019Variant summary: BRCA1 c.3607C>T (p.Arg1203X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 1.2e-05 in 251014 control chromosomes. c.3607C>T has been reported in the literature in numerous individuals affected with hereditary or early-onset breast and/or ovarian cancer (ie. Friedman_1994, Meindl_2002, Kim_2012, Juwle_2012, Solano_2013, Stavropoulo_2013). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. 16 clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar (after 2014). All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsNov 05, 2021The p.R1203* pathogenic mutation (also known as c.3607C>T), located in coding exon 9 of the BRCA1 gene, results from a C to T substitution at nucleotide position 3607. This changes the amino acid from an arginine to a stop codon within coding exon 9. This alteration has been reported in multiple families with breast and/or ovarian cancer across various ethnicities (Friedman LS et al. Nat. Genet. 1994 Dec;8:399-404; Zhang S et al. Gynecol. Oncol. 2011 May;121:353-7; Walsh T et al. Proc. Natl. Acad. Sci. U.S.A. 2011 Nov;108:18032-7; Juwle A et al. Med. Oncol. 2012 Dec;29:3272-81; Hirasawa A et al. Jpn. J. Clin. Oncol. 2014 Jan;44:49-56; Konstantopoulou I et al. Clin. Genet. 2014 Jan;85:36-42; Meisel C et al. Arch. Gynecol. Obstet. 2017 May;295:1227-1238). Of note, this alteration is also designated as 3726C>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. -

This variant has been observed in over ten individuals and families affected with breast and ovarian cancer (PMID: 22006311, 22752604, 22798144, 23961350, 23536787, 24010542, 24218521, 25452441, 28324225, 28993434, 29310832, 29339979, 29470806, 29752822, 30555256, 30720863, 31372034, 33151324, 33471991; Leiden Open Variation Database DB-ID BRCA1_001405) and an individual affected with clear cell renal cell carcinoma (PMID: 33442023). This variant has been identified in 3/251014 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. -

This variant has been widely reported in individuals with hereditary breast and ovarian cancer (see for example, Table 2a, Friedman et al. 1994. PubMed ID: 7894493; Table 1, Meindl et al. 2002. PubMed ID: 11802209). This variant was also reported as germline variant in a patient with renal cell carcinoma (Table S3, Santos et al. 2021. PubMed ID: 33442023). This variant is reported in 0.0055% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-41243941-G-A), and it is interpreted as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/17671/).
