Genes affected

RAD51C (HGNC:9820): (RAD51 paralog C) This gene is a member of the RAD51 family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51 and are known to be involved in the homologous recombination and repair of DNA. This protein can interact with other RAD51 paralogs and is reported to be important for Holliday junction resolution. Mutations in this gene are associated with Fanconi anemia-like syndrome. This gene is one of four localized to a region of chromosome 17q23 where amplification occurs frequently in breast tumors. Overexpression of the four genes during amplification has been observed and suggests a possible role in tumor progression. Alternative splicing results in multiple transcript variants.

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 RAD51C p.Ala126Thr variant was identified in 70 of 11449 proband chromosomes (frequency: 0.006) from individuals or families with hereditary breast and ovarian cancer (Akbari_2010_20723205, Blanco_2014_25086635, Clague_2011_21980511, Coulet_2013_22725699, Jonson_2015_26740214, Kushnir_2012_23117857, Leeneer_2012_22370629, Lu_2012_22476429, Meindl_2009_20400964, Romero_2011_ 21537932, Scheckenbach_2014_24315737, Thompson_2012_21990120, Vuorela_2011_21750962, Wong_2011_21409391). The variant was also identified in dbSNP (ID: rs61758784) as â€šÃ„ÃºWith other alleleâ€šÃ„Ã¹, ClinVar (as likely benign by PreventionGenetics and Counsyl, as benign by Invitae, GeneDx, Ambry Genetics, Color Genomics, and Quest Diagnostics), Clinvitae (as benign and likely benign), LOVD 3.0 (9x), and Zhejiang Colon Cancer Database (2x). The variant was not identified in Cosmic or MutDB databases. The variant was identified in control databases in 955 of 275828 chromosomes (3 homozygous) at a frequency of 0.003462 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 28 of 23954 chromosomes (freq: 0.001169), Other in 31 (1 homozygous) of 6444 chromosomes (freq: 0.004811), Latino in 109 (1 homozygous) of 34292 chromosomes (freq: 0.003179), European (Non-Finnish) in 684 (1 homozygous) of 125890 chromosomes (freq: 0.005433), Ashkenazi Jewish in 43 of 10090 chromosomes (freq: 0.004262), European (Finnish) in 8 of 25752 chromosomes (freq: 0.000311), and South Asian in 52 of 30556 chromosomes (freq: 0.001702), while the variant was not observed in the East Asian populations. The variant is classified as a benign polymorphism in the literature (Akbari_2010_20723205, Clague_2011_21980511, Coulet_2013_22725699, Jonson_2015_26740214, Kushnir_2012_23117857, Leeneer_2012_22370629, Lu_2012_22476429, Meindl_2009_20400964, Osorio_2012_22451500). In vivo yeast functional studies have shown no detectable difference in expression versus the wild type allele (Clague_2011_21980511). In addition, Jonson (2015_26740214) has reported that the variant to be co-occurring in three individuals with a disease-causing RAD51C (c.945dupT), BRCA1 (p.Gln563Ter) or BRCA2 (c.5164_5165delAG) mutation, increasing the likelihood that the p.Ala126Thr variant does not have clinical significance. The p.Ala126Thr residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
