Figure 1.
Oncoprint visualization of molecular alterations in the MMR genes in triple-negative breast cancer. Alterations across all breast cancer subtypes are color-coded on the basis of the legends on the bottom. Each column represents a sample, each row an MMR gene. Somatic MMR mutations (A) are seen in 35 (2%) of queried patients from MSK study with the majority showing missense mutation, while MMR mRNA alterations (B) in n = 363 (19%) from METABRIC study. Tumors included in this analysis have been retrieved from cbioportal.org.
