Summary
Brief summary (as posted)
Background. Cancer is the leading cause of death by disease in children. Most pediatric tumors differ from adult tumors in terms of biological and clinical characteristics. In children, the part of genetic determinism could be higher since the role of environmental factors may be less pronounced than in adults and that a young age at onset is a main feature of genetic cancer predisposition. Recent studies suggested that a number of genetic predisposition remains to be characterized. Methods. Trio-Based whole exome sequencing of germline DNA from patients (children and adults diagnosed with cancers between 0 and 17 years) and parents will be performed prospectively in a multicentric study including 40 unselected cases of malignant tumor. Participating hospitals will include the CHU of Montpellier, the CHU de Nice and the AP-HP. Tumor analysis will include whole exome analysis and transcriptome for the identification of therapeutic target and contribute to confirm potential link between constitutive mutations and tumor phenotype (such as loss of expression, loss of heterozygosity). Perspectives. This pediatric oncology study proposing a global approach integrating trio-based whole exome sequencing, somatic DNA and RNA analysis will improve the recognition of genetic predisposition and the characterization of target therapies in children with cancer.

- description
- A blood sample will be taken from patients and their parents in order to carry out genetic analyses. New generation NGS Exome sequencing in trio (patient and 2 healthy parents) on an Illumina HiSeq 2000 platform using the SureSelectXT Human All Exon 50Mb, V5 kit. Bioinformatics analysis of the data. Confirmation of mutations by Sanger sequencing (gold standard). In case of identification of mutations in candidate genes confirmed by Sanger sequencing, we will perform functional and clinical-genetic studies.
