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 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. -

Variant summary: BRCA1 c.4410A>T (p.Glu1470Asp) 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 allele was found at a frequency of 1.6e-05 in 251242 control chromosomes, predominantly at a frequency of 8.7e-05 within the Latino subpopulation in the gnomAD database. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.4410A>T has been reported in the literature in individuals with a personal and/or family history of breast/ovarian cancers (examples : Judkins_2005, Borg_2010, Dutil_2012, Diaz-Zabala_2018, Matta_2022). However, these reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrences with the same pathogenic variant have been reported in 3 separate individuals (BRCA2 c.3922G>T, p.Glu1308X; NHGRI BIC and internal testing), providing supporting evidence for a benign role. At least two publications report experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant (example, Woods_2016, Fernandes_2019, Nepomuceno_2022). The following publications have been ascertained in the context of this evaluation (PMID: 24728327, 20104584, 21520273, 30400234, 22682623, 30765603, 27843123, 16267036, 36329109, 36171434, 30212499, 28781887). ClinVar contains an entry for this variant (Variation ID: 89064). Based on the evidence outlined above, the variant was classified as likely benign. -
