Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate immune function in BRCA1/2 mutation carriers without cancer, specifically to determine whether immune function in healthy individuals with germline loss of function BRCA1/2 mutations, impacts overall immune health and fitness.
