BRCA2 and Inherited cancer-predisposing syndrome: Of the four remaining germline false positive results, three (RB1 K874Q, MSH6 S405C, BRCA2 splice site mutation at the junction of exons 2 and 3 (g.32890665G > A)) were classified as uncertain clinical utility and only one, a known pathogenic variant associated with hereditary cancer syndromes (TP53 R248Q), was classified as having potential clinical utility based on negative prognostic implications (Fig. 1d).
