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]

The p.P1502S variant (also known as c.4504C>T), located in coding exon 13 of the BRCA1 gene, results from a C to T substitution at nucleotide position 4504. The proline at codon 1502 is replaced by serine, an amino acid with similar properties. Using an in vivo prediction tool, this variant was predicted to create an additional kinase binding site (Tram E et al. PLoS ONE 2013; 8(5):e62468). This amino acid position is poorly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This variant is denoted BRCA1 c.4504C>T at the cDNA level, p.Pro1502Ser (P1502S) at the protein level, and results in the change of a Proline to a Serine (CCA>TCA). This variant was predicted to create additional kinase binding sites, the clinical significance of which is unclear (Tram 2013). BRCA1 Pro1502Ser was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Proline and Serine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. BRCA1 Pro1502Ser occurs at a position that is highly variable across species and is located in the SQ/TQ cluster domain (Roy 2012). In addition, in silico analyses predict that this variant is unlikely to alter protein structure or function. The variant is listed once in the Breast Information Core (BIC) database as having unknown significance. Based on currently available information, it is unclear whether BRCA1 Pro1502Ser is pathogenic or benign. We consider it to be a variant of uncertain significance. -

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1502 of the BRCA1 protein (p.Pro1502Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 55218). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt BRCA1 protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
