Ordering Recommendation

Recommended test to confirm a hereditary cause of central nervous system (CNS) cancer in individuals with a personal or family history. Testing minors for adult-onset conditions is not recommended; testing will not be performed in minors without prior approval. For additional information, please contact an ARUP genetic counselor at 800-242-2787 ext. 2141.
