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

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Variant Summary: The c.1511G>A variant involves the alteration of a non-conserved nucleotide and 3/4 in silico tools predict a benign outcome. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.007% (8/121170), which does not exceed the maximal expected allele frequency for a pathogenic variant in BRCA1 (0.10%). However, the frequency data should still suggest that this variant is likely to be a rare polymorphism. The variant has been reported to co-occur with many deleterious pathogenic variants in BRCA1, such as c.70_80del (8 times in BIC), c.78_79insCATCTG (1 time in BIC) and p.Ser510Ter (1 time in BIC). A publication (Tavtigian_2006) also reported co-occurrence with an unspecified deleterious BRCA1 variant in six samples. (Presence of a variant in trans with another deleterious variant in BRCA1 is a definite evidence of benign outcome and thus it is very likely that the reported co-occurrence information is in line with this notion.) Studies presenting multifactorial probability based models report the variant as a neutral variant (Easton_2007, Lindor_2012). In addition, multiple reputable databases/clinical diagnostic laboratories have classified the variant as neutral/likely benign/benign. Taken together, this variant is classified as Benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as 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. -
