Figure 2. The Landscape of Somatic Driver Alterations in the Breast International Group 1-98 Trial.

Only somatic driver alterations with a weighted frequency of 4% or greater in the whole cohort are displayed. All percentages shown are weighted frequencies with the exception of estrogen receptor (ER) and progesterone receptor (PR) expression. Luminal-like status was determined using the published St Gallen 2013 consensus.¹⁹ Thirteen patients were luminal-like status unknown because of missing data. Numbers in parentheses indicate absolute numbers of patients per cohort and subtype. Indels indicates insertions and deletions; LN, lymph node.
