Invitae | RCV000458817 | SCV000549361 | pathogenic | Hereditary breast ovarian cancer syndrome | 2016-05-26 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, truncating variants in BRCA1 are known to be pathogenic (PMID: 20104584). A different variant that causes a frameshift at the same codon, c.4065_4068del (p.Asn1355Lysfs*10), has been reported in many individuals and families with breast and/or ovarian cancer (PMID: 23199084). This sequence change deletes 3 nucleotides and inserts 1 nucleotide in exon 10 of the BRCA1 mRNA (c.4064_4066delinsT), causing a frameshift at codon 1355. This creates a premature translational stop signal (p.Asn1355Lysfs*12) and is expected to result in an absent or disrupted protein product. |
