Recommended core educational guidelines for family practice residents This document has been endorsed by the American Academy of Family Physicians and was developed in cooperation with the American College of Medical Genetics, the Association of Professors of Human and Medical Genetics, the Association of Departments of Family Medicine, the Association of Family Practice Residency Directors and the Society of Teachers of Family Medicine. Attitudes
The resident should develop attitudes that encompass the following:
A. Recognition of the importance of the family physician, the medical geneticist and the genetics team as collaborators in the evaluation, diagnosis and management of patients referred for genetic consultation.
B. Recognition of the need for sensitivity to the patient's and family's concerns relating to referral for genetic evaluation and diagnosis of a genetic disorder.
C. Recognition of the importance of confidentiality, ethical and legal issues involved in medical genetics.

C. Identification of pertinent community groups addressing the needs of patients and families with genetically based disorders
D. Basic genetic counseling for family physicians Implementation
The implementation of this curriculum component should take place during the longitudinal learning experiences throughout the 36 months of training. The curricular content should be integrated into the conference schedule and into teaching activities in the family practice center. Relevant resource and patient information materials should be available in the residency library.
