Allele frequency distribution of somatic variants in (a) tumour and (b) plasma samples. All refers to all somatic variants in the sample; shared refers to variants which were shared between matched tumour and plasma samples and unique refers to variants which were only present in either tumour or plasma samples. Samples 065 and 098 were from benign tumour patients and other samples were from breast cancer patients
