Invitae RCV000465250 SCV000549302 pathogenic Hereditary breast and ovarian cancer syndrome 2019-12-11 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 16 of the BRCA1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with breast cancer and/or ovarian cancer (PMID: 25556971, 27914478, 28717669, 29339979, 29446198). This variant is also known as IVS17+2T>C in the literature. ClinVar contains an entry for this variant (Variation ID: 37631). Experimental studies have shown that this variant disrupts mRNA splicing and/or protein function (PMID: 30209399). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). For these reasons, this variant has been classified as Pathogenic.
