title: Whole exome sequencing for primary breast cancer and lymph node metastasis samples
design: For whole exome sequencing (WES), exomes were captured with the SureSelect XT Human All Exon V5 kit (Agilent) then libraries were constructed using TruSeq Rapid PE Cluster kit (Illumina). Constructed libraries were sequenced by HiSeq 2500 systems (Illumina) with the 100-bp paired-end mode using TruSeq Rapid SBS kit (Illumina).
