Fig. 3From: Whole-exome sequencing of BRCA-negative breast cancer patients and case–control analyses identify variants associated with breast cancer susceptibilitySanger sequencing validation of variants identified by whole-exome sequencing. Representative sequencing chromatograms showing the different variants found in our breast cancer patients and of an unaffected control. A Seven variants were confirmed by Sanger sequencing. B Three variants failed to be validated by Sanger sequencing. Arrows indicate the position of the variantBack to article page
