Brief Summary:

RATIONALE: Identifying genes related to cancer may help in the study of cancer. It may also help doctors predict who is at risk of developing neuroblastoma.

PURPOSE: This laboratory study is looking at genes in participants with neuroblastoma or noncancerous conditions.


Condition or disease Intervention/treatment
Neuroblastoma Genetic: gene mapping Genetic: polymorphism analysis

Detailed Description:

OBJECTIVES:

  • Perform a whole genome scan for association of neuroblastoma with single nucleotide polymorphisms (SNP) and SNP haplotypes.
  • Identify true disease-associated SNP alleles using a customized genotyping platform enriched for haplotype analyses in an independent sample set.
  • Validate disease-associated SNP alleles and haplotypes in a final independent sample set.
  • Identify neuroblastoma predisposition genes.

OUTLINE: This is a multicenter study. Participants are stratified according to presence of high-risk disease (yes vs no) and MYCN amplification (yes vs no).

DNA samples are derived from participants' banked blood or uninvolved bone marrow. A whole genome scan of DNA samples is employed to identify candidate single nucleotide polymorphisms (SNPs). The candidate SNPs are investigated, using a gene-centric haplotyping approach, to identify 10-20 true disease-associated alleles. The disease-associated alleles are again investigated, using a gene-centric haplotyping approach, to validate 5-10 disease-associated SNPs. SNPs are then analyzed for heritable predisposition.

Patients do not receive the results of the genetic testing.

A certificate of confidentiality protecting the identity of research participants in this project has been issued by the Children's Oncology Group.

PROJECTED ACCRUAL: A total of 4,675 patients and 4,675 controls will be accrued for this study.
