Is there a genetic test that shows who is at risk for osteogenic sarcoma?

Not really.: Unless your family has a documented history of this, and a particular mutation has been identified in other family members, there is not an established test for this condition.

OS and gene: Some of the sarcomas can run in families and clusters. Some of them can present with other malignancies in family. I think gene testing for p53 mutation can be done if there are other types if cancers besides os. There is no specific genetic test for os.
