The PTEN Cleveland Clinic score risk assessment tool for estimating risk of PTEN mutation was devised for use by health professionals. It should be noted that many features as described are best recognized by specialist medical/genetics professionals, and underestimation of risk may occur if the tool is not accurately completed. The results should be interpreted in the light of personal history, family history and physical examination performed by a medical/genetics professional. Patients may identify a genetic counselor near them by visiting the National Society of Genetic Counselors’ website www.nsgc.org).
