CNV profiles according to HER2 status. A The oncoplot of segments with an alteration frequency greater than 9% in the six subtypes in our NGS database. B The frequency distribution stratified by HR and HER2 status of the most common segments with amplifications from different subgroups in our NGS database. The lollipop plot was mapped by the “barplot” R package. C Oncoplot of the distribution of genomic alterations in different clusters in the whole cohort. D Comparison of the percentage of molecular clusters among the different subtypes. The P value was calculated by the Chi-square test based on the number of cases per group featuring the Cluster 1, Cluster 2 or Cluster 3 phenotype
