Illumina Clinical Services Laboratory,Illumina RCV000256646 SCV000915765 pathogenic Breast-ovarian cancer, familial 1 2017-09-12 criteria provided, single submitter clinical testing The BRCA1 c.3122C>G (p.Ser1041Ter) variant is a stop-gained variant that has been reported in two studies and detected in four individuals with breast or ovarian cancer (Li et al. 2008; Kim et al. 2016). Li et al. (2008) report one individual with breast cancer and a family history of the disease and Kim et al. (2016) report three more individuals with breast or ovarian cancer. All the affected individuals are from mainland China. Control data are unavailable for the p.Ser1041Ter variant and frequency information is not available from the 1000 Genomes Project, the Exome Sequencing Project, the Exome Aggregation Consortium or the Genome Aggregation Database. The p.Ser1041Ter variant is predicted to truncate 44% of the BRCA1 protein, and Ser1041 is predicted to be a phosphorylation site (Savas et al. 2005). Based on the evidence and the potential impact of stop-gained variants, the p.Ser1041Ter is classified as pathogenic for hereditary breast and ovarian cancer. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
