Brief Summary
This research trial studies deoxyribonucleic acid (DNA) samples from younger patients with germ cell tumor and their parents or siblings. Studying samples of tumor tissue and saliva from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

Outcome Measures
Primary Outcomes (1)
Pediatric GCT associated with genetic susceptibility
Will be modeled using a Poisson regression. A likelihood ratio test determines the statistical significance.
Up to 5 years
Secondary Outcomes (2)
List of genes that distinguish between the three most common histologic subtypes of pediatric GCT: yolk sac tumor, teratoma, and germinoma
Up to 5 years
Validation of array results by pyrosequencing
Up to 5 years
Study Arms (1)
Correlative studies
Patients and parents or siblings undergo saliva sample collection. DNA extracted from saliva samples and from patients' archived tumor tissue samples is genotyped and analyzed by methylation arrays, including methylation-specific PCR (pyrosequencing) assays. Genetic variation between pediatric germ cell tumors and parent or sibling is also analyzed. Patients' and family members' health history, demographics, and environmental exposures are collected by questionnaires or telephone interviews. Medical history, such as chronic conditions, prescribed medications and congenital abnormalities, including cryptorchidism, is also collected. Birth characteristics of the child, including birth weight and gestational age, are also captured.

Eligibility Criteria
You may qualify if:
- The patient is enrolled on COG-ACCRN07
- The patient has a primary diagnosis of germ cell tumor (GCT) including germinoma (ICCC 9060-9065) teratoma (9080-9084), embryonal carcinoma (9070-9072), yolk sac tumor (9071),choriocarcinoma (9100, 9103, 9104), and mixed GCT (9085, 9101, 9102, 9105) in all sites including the brain and central nervous system and registered with Children's Oncology Group (COG) by a North American member institution
- The patient must be diagnosed with a germ cell tumor between July 1, 2008 and December 31, 2015
- The patient must be \< 20 years of age at the time of diagnosis
- The patient must have at least one biological parent alive and willing to participate
- In the event that one case parent cannot contribute DNA, a case sibling, defined as the biological brother or sister of the study subject, may donate instead
- All questionnaire respondents must understand English or Spanish
- Concomitant treatment on a therapeutic trial is not required
