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]

This variant changes 1 nucleotide in exon 10 of the BRCA1 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 over ten individuals and families affected with breast and ovarian cancer (PMID: 9452076, 12181777, 15955237, 16162645, 18159056, 22006311, 22711857, 25371446, 25682074, 27425403, 27553291). This variant has been identified in 1/250916 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. -

Variant summary: BRCA1 c.3598C>T (p.Gln1200X) 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 4e-06 in 250916 control chromosomes (gnomAD). c.3598C>T has been reported in the literature in multiple individuals and families affected with Hereditary Breast And Ovarian Cancer Syndrome (e.g. Tartaglini_1998, Liede_2002, Judkins_2005, Latimer_2005, Beetstra_2006, John_2007, Torres-Mejia_2015, Rebbeck_2018). These data indicate that the variant is very likely to be associated with disease. Eleven ClinVar submitters including an expert panel (ENIGMA) (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Gln1200*) 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 (rs62625307, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with breast and ovarian cancer (PMID: 9452076, 22006311, 22711857, 24333842, 25682074). This variant is also known as 3717C>T. ClinVar contains an entry for this variant (Variation ID: 54929). For these reasons, this variant has been classified as Pathogenic. -

The BRCA1 c.3598C>T (p.Gln1200*) variant causes the premature termination of BRCA1 protein synthesis. This variant has been reported in the published literature in individuals with breast and/or ovarian cancer (PMIDs: 35377489 (2022), 33758026 (2022), 33606809 (2021), 33471991 (2021) see also LOVD (https://databases.lovd.nl/shared/), 31742824 (2020), 31528241 (2019), 31454914 (2019), 29161300 (2017), 28888541 (2017), 27553291 (2016), 25371446 (2014), 22006311 (2011), 18159056 (2007), 16162645 (2006), 15955237 (2005)). The frequency of this variant in the general population, 0.000004 (1/250916 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity.

The p.Q1200* pathogenic mutation (also known as c.3598C>T), located in coding exon 9 of the BRCA1 gene, results from a C to T substitution at nucleotide position 3598. This changes the amino acid from a glutamine to a stop codon within coding exon 9. This mutation has been identified in multiple individuals/families with hereditary breast and ovarian cancer (HBOC) syndrome (Tartaglini E et al. Hum. Mutat. 1998;Suppl 1:S163-6; Liede A et al. Am J Hum Genet, 2002 Sep;71:595-606; Latimer JJ et al. BMC Med. Genet. 2005 Jun;6:26; John EM et al. JAMA, 2007 Dec;298:2869-76; Walsh T et al. Proc. Natl. Acad. Sci.

Of note, this alteration is also designated as 3717C>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. -

The BRCA1 c.3598C>T variant is predicted to result in premature protein termination (p.Gln1200*). This variant has been reported to be causative for breast and ovarian cancer (Walsh et al. 2011. PubMed ID: 22006311; Alsop et al. 2012. PubMed ID: 22711857, Supplementary Table 2; Wong-Brown et al. 2015. PubMed ID: 25682074). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD. This variant is interpreted as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/54929/evidence/). Nonsense variants in BRCA1 are expected to be pathogenic. This variant is interpreted as pathogenic. -
