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: The BRCA1 c.5576C>G (p.Pro1859Arg) variant involves the alteration of a non-conserved nucleotide and 2/4 in silico tools (SNPsandGO not captured due to low reliability index) predict a benign outcome. Multiple functional studies support these benign predictions, to which the variant was found to act comparable to wild type function for homology directed repair and transcription activation. This variant was found in 3/120890 control chromosomes at a frequency of 0.0000248, which does not exceed the estimated maximal expected allele frequency of a pathogenic BRCA1 variant (0.0010005). Multiple publications have cited the variant in affected individuals, although with limited information (ie, lack of co-occurrence and/or cosegregation data). BIC has cited the variant to co-occur with a pathogenic BRCA2 variant, c.5073_5074insA (classified as pathogenic by LCA). Furthermore, multipe publications have predicted the variant to be "neutral," along with multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Therefore, taking all available lines of evidence into consideration, the variant of interest has been classified as Benign. -

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. -
