Study Description

Brief Summary: RATIONALE: Collecting and storing samples of bone marrow and blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at lymphoblasts in young patients with high-risk acute lymphoblastic leukemia.

Detailed Description: OBJECTIVES: * Identify regions of copy number abnormalities (CNA) and uniparental disomy in leukemic lymphoblasts from pediatric patients with high-risk acute lymphoblastic leukemia (ALL) using Affymetrix GeneChip Mapping 500K array sets. (Pilot project) * Identify regions of CNA and loss-of-heterozygosity using Affymetrix SNP 6.0 microarrays. (Expansion project) * Define gene expression profiles for leukemic lymphoblasts using Affymetrix U133 Plus 2.0 arrays. * Assess the global expression of microRNAs in leukemic lymphoblasts using microRNA gene chips. * Utilize array-generated gene expression data and data for CNAs and uniparental disomy to prioritize candidate genes and genomic regions for resequencing. * Characterize epigenomic profiles using the HpaII tiny fragment Enrichment by Ligation-mediated PCR (HELP) assay. (Expansion project) * Discover candidate therapeutic targets for these patients by identifying genes that are consistently mutated in leukemic lymphoblasts using high-throughput focused gene resequencing. (Pilot project) * Discover candidate therapeutic targets for these patients by next generation sequencing technologies, including whole genome, whole transcriptome, and whole exome. (Expansion project) OUTLINE: This is a multicenter study. Banked biological samples (bone marrow and peripheral blood) are analyzed using gene expression profiling, single-nucleotide polymorphism and genotyping assays, DNA copy number and loss of heterozygosity estimates, epigenetic profiling, and gene resequencing. PROJECTED ACCRUAL: A total of 150 patient samples will be accrued for this study.
