From: Landscape of somatic allelic imbalances and copy number alterations in HER2-amplified breast cancer
Prevalence of subclonal CN loss in breast cancer. Prevalence of subclonal CN loss was estimated in 99 HER2-amplified cases and 308 HER2-negative cases with PAM50 subtype classification analyzed by SNP arrays revealing differences in the frequency of subclonal CN loss events between subgroups. Top-axis indicates total number of cases for each bar. P-value was calculated using the Chi-square test for indicated groups.
