Fig. 2: Estimated genetic ancestry distribution in BEST TNBC RNA-seq cohort.

Genetic ancestry was estimated from genotypes from multi-locus SNP genotype data with 1000Genomes as the reference. A Relative proportion of ancestry estimation per participant with TNBC from the BEST cohort. B Distribution of participants with “High” proportional West African ancestry (Red) vs. “Low” relative to European ancestry (Blue). C TNBC subtype distribution based on “High” and “low” proportional West African ancestry. D Heatmap of unsupervised hierarchical clustering of ancestry proportion in the BEST cohort (“High” proportional West African ancestry in red vs. “Low” in blue), shown with associated TNBC subtypes.
