Acute myeloid leukemia (AML) is a clinically and molecularly heterogeneous disease.1 This concept has been supported by more than 4 decades of studies showing distinct outcomes of subsets of patients that differ in age, disease type (primary vs secondary vs therapy-related), and cytogenetic and...
Genomic and Epigenomic Characterization of Acute Myeloid Leukemia
In a study by the Cancer Genome Atlas Research Network reported in The New England Journal of Medicine, genomes of 200 adult cases of de novo acute myeloid leukemia (AML) were analyzed by whole-genome sequencing (n = 50) or whole-exome sequencing (n = 150) to identify mutations and relationships...
Supreme Court Rules Human Genes May Not Be Patented
On June 13, the U.S. Supreme Court ruled unanimously that isolated human genes may not be patented.
