Germ Cell Tumor and Testicular Tumor DNA Registry
Germ Cell Tumor and Testicular Tumor DNA Registry
This study is being done to create a registry to help us learn more about germ cell tumors
 (GCT) and other testicular tumors. The registry will include people with these tumors and
 also relatives and unrelated people without these tumors. This study will help us learn more
 about the prevention, diagnosis, treatment and outcome of these tumors. Studying relatives of
 patients and people unrelated to patients with GCT and other testicular tumors will help us
 understand why some people get these tumors and why some people don't.

 Family Member Cohort
