Predictive Genetic Risk Assessment Trial (PGT)

This study has been completed.
Information provided by:
Mayo Clinic Identifier:
First received: October 29, 2008
Last updated: April 25, 2011
Last verified: April 2011
This proof-of-principle clinical trial at Mayo Clinic studies how patients and their physicians understand and utilize predictive genetic risk assessment. A critical goal of this clinical trial is to understand how individual patients and their doctors perceive and respond to genetic risk information that is largely uncertain.

Condition Intervention
Colon Cancer Lung Cancer Atrial Fibrillation Diabetes Type 2 Obesity Breast Cancer Graves Disease Osteoarthritis Celiac Disease Myocardial Infarction Prostate Cancer Genetic: SNP analysis

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Proof-of-Principle Trial of Communication to Patients Receiving Predictive Genetic Risk Assessment
