Invitae RCV000047820 SCV000075833 pathogenic Hereditary breast and ovarian cancer syndrome 2019-08-29 criteria provided, single submitter clinical testing This sequence change deletes 2 nucleotides from exon 10 of the BRCA1 mRNA (c.2389_2390delGA), causing a frameshift at codon 797. This creates a premature translational stop signal (p.Glu797Thrfs*3) and is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA1 are known to be pathogenic. This particular variant has been reported in individuals affected with breast and ovarian cancer (PMID: 10634513, 25070656). This variant is also known as 2508delGA in the literature. For these reasons, this variant has been classified as Pathogenic.

Integrated Genetics/Laboratory Corporation of America RCV000047820 SCV000918700 pathogenic Hereditary breast and ovarian cancer syndrome 2019-06-07 criteria provided, single submitter clinical testing Variant summary: BRCA1 c.2389_2390delGA (p.Glu797ThrfsX3) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 250564 control chromosomes. c.2389_2390delGA has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (Yoshikawa_1999, Kawahara_2004, Kashima_2000, Alsop_2012, Luyeye Mvila_2014). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
