A combinatorial approach for analyzing intra-tumor heterogeneity from high-throughput sequencing data.

Abstract excerpt

MOTIVATION: High-throughput sequencing of tumor samples has shown that most tumors exhibit extensive intra-tumor heterogeneity, with multiple subpopulations of tumor cells containing different somatic mutations. Recent studies have quantified this intra-tumor heterogeneity by clustering mutations into subpopulations according to the observed counts of DNA sequencing reads containing the variant allele. However,...
