Invitae RCV000205711 SCV000259433 uncertain significance Hereditary breast ovarian cancer syndrome 2015-07-16 criteria provided, single submitter clinical testing This sequence change is a gross duplication of the genomic region encompassing exons 1 and 2 of the BRCA1 gene. It is present in tandem and extends approximately 360 kb upstream of exon 1, and 19 nucleotides downstream of exon 2. Gross duplications that include exons 1 and 2 of the BRCA1 gene have been reported in individuals with breast and/or ovarian cancer (PMID: 19894111, 23996866, 24686251). Segregation with disease or impact on BRCA1 function of these duplications have not been reported, and their breakpoints relative to this duplication are not known. Because the effect of this duplication on BRCA1 mRNA expression and protein function are unknown, this variant has been classified as a Variant of Uncertain Significance.
