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]

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: BRCA1 c.4750G>T (p.Ala1584Ser) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 251362 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.4750G>T has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (Borg_2010, Capanu_2011), without strong evidence for causality. In a large study evaluating breast cancer cases and controls in the Breast Cancer Association Consortium (BCAC), the variant was reported in 2/60466 cases, but was also found in 1/53461 controls (Dorling_2021 through LOVD). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrences with other pathogenic variant(s) have been reported at our lab (BRCA1 c.4756G>T, p.Glu1586Ter), providing supporting evidence for a benign role. At least one publication reports experimental evidence evaluating an impact on protein function using transcriptional activation assay at a high-throughput manner with many other variants in BRCA1 (Fernandes_2019). These results showed no damaging effect of this variant. The following publications have been ascertained in the context of this evaluation (PMID: 20104584, 21520273, 33471991, 30765603, 15385441, 23704879). ClinVar contains an entry for this variant (Variation ID: 55279). Based on the evidence outlined above, the variant was classified as likely benign. -

Feb 25, 2019
Ambry Genetics
Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
