Studying Genes in Samples From Younger Patients With Adrenocortical Tumor

Using New Approaches for Genomics Studies in Pediatric Adrenocortical Tumors: Whole Genome Sequencing; Deep Sequencing; miRNA; methDNA and SNP 6.0

RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research trial studies genes in samples from younger patients with adrenocortical tumor.

OBJECTIVES:

• To perform whole-genome sequencing, deep sequencing, micro RNA analysis, methylation status, copy number variation analysis, and single-nucleotide polymorphisms (SNPs) analysis in pediatric adrenocortical tumors and compare those results to those of the same patient's normal cells.

OUTLINE: Archived tumor and blood samples are analyzed for whole-genome sequencing, deep sequencing, micro RNA , methylation status, copy variation, and single-nucleotide polymorphisms. Results are then compared with patients' normal cells.

DISEASE CHARACTERISTICS:
