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]

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. -

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.
