Abstract:Genome-wide single nucleotide polymorphism (SNP) analyses have revealed uniparental disomy (UPD) to be a common event in cytogenetically normal acute myeloid leukemia (CN-AML) occurring in approximately 20% of cases. Acquired UPD results in copy number neutral loss of heterozygosity (LOH). Comparing matched tumor and germline DNA samples recurrent acquired UPDs affecting chromosomes 11p and 13q were identified. As DNA microarray-based gene expression profiling (GEP) has recently been shown to powerfully captur… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
