Cancer Variant Interpretation Group UK,Institute of Cancer Research, London RCV000709466 SCV000897862 pathogenic Hereditary breast and ovarian cancer syndrome 2018-10-31 criteria provided, single submitter clinical testing Data included in classification: The variant was observed in 2 independent UK families undergoing clinical diagnostic testing, the denominator of which dataset of clinical testing was 16,600. Case control comparison against ethnically matched population data (2/16,600 in familial cases against 0/63,369 GNOMAD NFE controls pexact= 0.04 (PS4). The variant is absent in the remainder of the GNOMAD populations (75,263 individuals) (PM2). Predicted deleterious on SIFT, Align GVGD and Polyphen HumVar (PP3). Non-functional in SGE haploid BRCA1-assay (Findlay et al. 2018), an assay well validated against ENIGMA/ClinVar (PS3) The variant is located in the BRCT1 domain (PM1_sup). c.4963T>C p.(Ser1655Pro) previously classified as pathogenic by CanVIG (July 2018) (PM5). Data not included in classification: Extensive additional functional data demonstrating variant to be deleterious: Williams et al. Carvalho et al. Lee et al., Bouwman et al (2013), Domchek et al (2013), Shakya (2011). Anantha et al (2017) elife; 6 e21350 Apr: undertook functional studies confirming reduced HR activity. Computer based algorithms predicting variant to be deleterious: Iverson (2012), Gomez-Garcia (2009) and Karchin (2007). Segregation 1 in 4 in UK family. Gomez-Garcia et al (2009) demonstrated segregation in 6/6 individuals (across 2 families) but no further details provided. There are additional reports of this variant in ClinVar (2), BIC (3) and BRCA1 LOVD (11).
