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: BRCA1 c.3640G>A (p.Glu1214Lys) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. However, comparative evolutionary approach for classifying the variant using mammalian BRCA1 sequences as performed by Burk-Herrick_2005 shows that this variant has low oncogenic score. The variant allele was found at a frequency of 9.9e-05 in 251288 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in BRCA1 causing Hereditary Breast And Ovarian Cancer Syndrome (9.9e-05 vs 0.001), allowing no conclusion about variant significance. c.3640G>A, has been reported in the literature in individuals affected with Breast and Ovarian Cancer in one family where it did not segregate with disease (example, Zuhlke_2004). Large multifactorial likelihood-ratio model study that included cosegregation, co-occurrence, and logistic regression analyses shows that this variant has high odds in favor of benign effect (Easton_2007). Similarly, in another multifactorial probability model study, this variant was shown to have very low odds in favor of causality (Lindor et al 2012). These data do not allow any conclusion about variant significance. At-least two co-occurrences with other pathogenic variant(s) have been reported in the BIC database and also observed at our laboratory (BIC-BRCA2 c.6833_6837delTCTTA, p.Ile2278fs; our laboratory-BRCA2 c.2095C>T, p.Q699X), providing supporting evidence for a benign role. Eight clinical diagnostic laboratories and an expert panel (ENIGMA) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All submitters classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

p.Glu1214Lys in exon 10A of BRCA1: This variant is classified as likely benign b ecause it did not segregate with disease in one family and since it has been ide ntified in 0.03% (12/3438)) of Latino chromosomes by the Genome Aggregation Data base (gnomAD, http://gnomAD.broadinstitute.org; dbSNP rs80356923). In addition, this variant was classified as benign on Aug 10, 2015 by the ClinGen-approved (E NIGMA) expert panel (ClinVar 54948). Computational prediction tools and conserva tion analysis suggest that the p.Glu1214Lys variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity.

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. -

The BRCA1 p.Glu1214Lys variant was identified in one individual with ovarian cancer and one family with hereditary prostate cancer; however, control chromosomes from healthy individuals were not included in these studies (Akbari 2011, Zuhlke 2004). The variant was also identified in dbSNP (ID: rs80356923) â€š With untested alleleâ€šÃ„Ã¹, LOVD, COSMIC, UMD (8X as a neutral variant), and the BIC database (9X with unknown clinical importance). This residue is conserved in mammals but not across lower organisms, and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. One in silico study by Tram (2013) suggests that the variant may affect protein binding to neighbouring nucleotides; however, two other in silico studies using a multifactorial likelihood-ratio model predict this variant to be neutral or likely not pathogenic (Easton 2007, Lindor 2012). However, Myriad has found this variant in trans with a known deleterious mutation and classify it as a polymorphism (personal communication). In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign. -
