Genetic Analysis Using Blood or Bone Marrow From Participants With Neuroblastoma or Noncancerous Conditions
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.
|Study Design:||Observational Model: Case-Only
Time Perspective: Cross-Sectional
|Official Title:||Genetic Basis of Neuroblastoma Tumorigenesis|
- Neuroblastoma predisposition genes [ Designated as safety issue: No ]
- Single nucleotide polymorphism (SNP) allele disease association [ Designated as safety issue: No ]
- SNP haplotype disease association [ Designated as safety issue: No ]
- Validation of SNP allele and haplotype disease association [ Designated as safety issue: No ]
- SNP association with phenotypic subsets (i.e., high-risk vs no high-risk disease; MYCN amplification vs no MYCN amplification) [ Designated as safety issue: No ]
Biospecimen Retention: Samples With DNA
Blood, Bone Marrow
|Study Start Date:||December 2006|
|Estimated Primary Completion Date:||January 2100 (Final data collection date for primary outcome measure)|
- 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.
