121. Genetic Testing in the Nutritional Evaluation: Clinical Utility and Challenges

Monday, October 22
3:30 PM - 5:00 PM
CE: 1.5

Session Level 3 - Advanced

Genetic testing has become mainstream, with many direct-to-consumer marketing options. This session will provide a clinical overview of genetic testing to include nutritional evaluation, current methods, progress, and challenges in the field. Dr. Posey will discuss key diagnoses that can be uncovered in the course of a thorough nutritional evaluation. She will also review the distinction between rare variants with large clinical effect and common variants with small clinical effect, and examine how these concepts are relevant to the interpretation of clinically available testing.

Planned with the Committee for Lifelong Learning
