RCV000254687 | SCV000150087 | likely pathogenic | not provided | 2018-04-30 | criteria provided, single submitter | clinical testing | This variant is denoted RAD51C c.706-2A>G or IVS4-2A>G and consists of an A>G nucleotide substitution at the -2 position of intron 4 of the RAD51C gene. The variant destroys a canonical splice acceptor site and is predicted to cause abnormal gene splicing, leading to an abnormal protein product. RAD51C c.706-2A>G was shown to result in skipping of exon 5, leading to the in-frame loss of 44 amino acids (Golmard 2013), and RNAseq analysis performed by Davy 2017 et al. revealed several splice products, the most predominant of which was exon 5 skipping, followed by a proportion of normal, wild-type transcript. This variant has been reported in association with breast and ovarian cancer (Walsh 2011, Loveday 2012, Golmard 2013, Couch 2015, Song 2015, Golmard 2017, Harter 2017, Kotoula 2017). Based on the current evidence, we consider this variant to be likely pathogenic. |

Invitae | RCV000234445 | SCV000291240 | pathogenic | Fanconi anemia, complementation group O | 2019-12-16 | criteria provided, single submitter | clinical testing | This sequence change affects an acceptor splice site in intron 4 of the RAD51C gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is present in population databases (rs587780259, ExAC 0.003%). This variant has been reported in the literature in several individuals with breast and ovarian cancer (PMID: 22006311, 22538716, 24549055, 25452441, 26261251, 26681312, 29255180). In one family, it was reported to segregate with ovarian cancer in two individuals (PMID: 24139550). ClinVar contains an entry for this variant (Variation ID: 128209). Experimental studies have shown that this sequence change disrupts normal mRNA splicing (PMID: 24139550, 22006311). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in RAD51C are known to be pathogenic (PMID: 20400964, 21990120, 24800917). For these reasons, this variant has been classified as Pathogenic. |

Integrated Genetics/Laboratory Corporation of America | RCV001194262 | SCV001363654 | pathogenic | Hereditary breast and ovarian cancer syndrome | 2019-01-02 | criteria provided, single submitter | clinical testing | Variant summary: RAD51C c.706-2A>G is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: Five predict the variant abolishes a 3' acceptor site. Experimental evidence demonstrated that this variant affects mRNA splicing leading to the loss of 44 amino acids in a functional domain of the protein by an in-frame exon 5 skipping (Golmard_2013). The variant allele was found at a frequency of 2.2e-05 in 277092 control chromosomes (gnomAD). c.706-2A>G has been reported in the literature in multiple individuals affected with Breast and Ovarian Cancer (Couch_2015, Golmard_2013). These data indicate that the variant is very likely to be associated with disease. Six ClinVar submissions from clinical diagnostic and research laboratories (evaluation after 2014) cite the variant as pathogenic (5x) and once as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
