•
•
•
If mutation found in Proband  May test relatives and if positive:
• FAP  Prophylactic TPC with IPAA at 18 yrs or later when diagnosed
• HNPCC  Screening colonoscopy 1-2 yearly
If mutation found in Proband  May test relatives and if negative:
• Average risk for relative
If no mutation found in Proband, diagnosis is already established CLINICALLY
• -ve genetic testing does not rule out either diagnosis
• Proband and families get treated or screened as they have disease
