Genes affected
BRCA2 (HGNC:1101): (BRCA2 DNA repair associated) Inherited mutations in BRCA1 and this gene, BRCA2, confer increased lifetime risk of developing breast or ovarian cancer. Both BRCA1 and BRCA2 are involved in maintenance of genome stability, specifically the homologous recombination pathway for double-strand DNA repair. The largest exon in both genes is exon 11, which harbors the most important and frequent mutations in breast cancer patients. The BRCA2 gene was found on chromosome 13q12.3 in human. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele. [provided by RefSeq, May 2020]

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.9501+9A>C variant is a BRCA2 intronic variant located at a position not widely known to affect splicing. 4/5 splicing prediction programs (via Alamut) suggest no significant effect on splicing, ESE finder predicts no change to binding motifs, and Mutation Taster predicts the variant to be a polymorphism. The observed allele frequency in controls including the large and diverse ExAC cohort is 4/121488(1/30372), which does not exceed the maximal expected alelle frequency for a pathogenic BRCA2 variant (1/1333). However, it has been reported to co-occur with several potentially pathogenic variant in BRCA2 (c.5909C>A, p.Ser1970X - UMD; BRCA2 c.5410_5411delGT (p.Val1804Lysfs) - BIC; BRCA2 c.9382C>T (p.Arg3128Ter) - BIC and BRCA1 IVS3+3A>C (Claes_2003). In addition, multiple reputable databases/clinical diagnostic labs (UMD, GeneDx, and SCRP) and publications (Lindor_2012 and Easton_2007) classify the variant as benign/neutral. Furthermore, functional studies from multiple independent publications report that the variant of interest does not affect splicing (Campos_2003, Claes_2003, Houdayer_2012, and Whiley_2011). Taken together, this BRCA2 intronic variant has been classified as Benign. -

Malignant tumor of breast Benign:1

Significance: Likely benign
Review Status: no assertion criteria provided
Collection Method: clinical testing

The BRCA2 c.9501+9A>C variant was identified in 1 of 820 proband chromosomes (frequency: 0.001) from individuals or families with breast and ovarian (Diez 2003) and was not identified in 200 control chromosomes from healthy individuals (Claes 2003). The variant was also identified in dbSNP (ID: rs81002867) as With other allele, ClinVar (classified as benign by GeneDx, ARUP, Color Genomics, Laboratory Corporation of America, Invitae, SCRP; as likely benign by Counsyl), Clinvitae, COGR (likely benign/benign), LOVD 3.0, UMD-LSDB (36X uncertain significance), BIC Database (unknown clinical importance). In UMD the variant was identified with a co-occurring pathogenic BRCA2 variant (c.5909C>A (p.Ser1970X), increasing the likelihood that the c.9501+9A>C variant does not have clinical significance. The variant was not identified in ARUP Laboratories, Zhejiang Colon Cancer Database, databases. The variant was identified in control databases in 17 of 276704 chromosomes at a frequency of 0.0001 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: “Other” in 1 of 6454 chromosomes (freq: 0.0002), Latino in 3 of 34398 chromosomes (freq: 0.0001), European in 13 of 126364 chromosomes (freq: 0.0001); but not in the African, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In addition, mRNA and bioinformatics analysis of the variant showed no alteration effect at the cDNA and protein level (Easton 2007, Campos 2003, Claes 2003, Houdayer 2012, Lindor 2012, Whiley 2011, Thery 2011). In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
