Comprehensive genetic analysis of pediatric germ cell tumors

Germ cell tumors (GCTs) are relatively rare tumors in children. Previous studies showed that adult testicular GCTs had some genomic alterations, but genetic basis of pediatric GCTs is still to be elucidated. We applied DNA methylation array analysis, whole-transcriptome sequencing, targeted capture sequencing, and SNP array analysis to fifty-one GCT samples.
