Brief Summary:
This study aims to assess how a polygenic risk score (PRS) reported with the results of multi-gene panel testing affects the breast cancer risk management recommendations healthcare providers make to their patients. The PRS is a score based on small genetic changes, clinical history, and family history. The PRS is used to estimate remaining lifetime risk of developing breast cancer for patients with no personal history of breast cancer and an overall negative result from MGPT.

Primary Outcome Measures :
  1. Change in Breast Cancer Risk Management Recommendations [ Time Frame: First recommendations will be made within 45 days of the initial study visit. Second recommendations will be made within 75 days of the initial study visit. ]
    Breast Cancer Risk Management Recommendations are recorded at two separate times; first recommendations will be recorded by the investigator or his/her designee based on the results of MGPT only. After these recommendations are recorded, the complete report including the PRS will be released. Then the healthcare provider will record recommendations again based on the results of MGPT and PRS. The difference between these recommendations will be used as a measure of the effect a PRS has on breast cancer risk management recommendations made by healthcare providers.


Biospecimen Retention:   Samples With DNA
Residual specimen may be maintained for an indefinite period of time at Ambry Genetics and be available for future studies as provided for in the consent document. Future studies on identifiable specimens or data will require review by an IRB or ethics committee.
