摘要

In this pilot study, we gsed primary human acute myeloid leukemia (AML) cell genomes as templates for exonic PCR amplification, followed by high-throughput resequencing, analyzing ≈ 7 million base pairs of DNA from 140 AML samples and 48 controls. We identified six previously described, and seven previously unde-scribed sequence changes that may be relevant for AML patho-genesis. Because the sequencing templates were generated from primary AML cells, the technique favors the detection of mutations from the most dominant clones within the tumor cell mixture. This strategy represents a viable approach for the detection of potentially relevant, nonrandom mutations in primary human cancer cell genomes.
