    • Accredited

This session will highlight complex diagnostic cases from the Undiagnosed Diseases Network (UDN). Expert clinicians will provide thorough summaries of cases that have defied conventional diagnostic approaches. Attendees will gain valuable insights into the multidisciplinary strategies employed by the UDN and provide input on additional diagnostic avenues to pursue.

This session is intended to enhance the participants' competence in diagnosing rare and undiagnosed diseases. By sharing real cases and experiences from the UDN, the session aims to broaden the participants' understanding of the complexities and challenges involved in these diagnostic dilemmas. The session also seeks to improve the participants' performance in approaching and solving diagnostic dilemmas, ideally contributing to improved patient outcomes by increasing the likelihood of accurate and timely diagnosis.

This session addresses several professional practice gaps in the field of medical genetics:
1. Diagnostic Challenges: Undiagnosed diseases often present unique diagnostic challenges due to their rarity and complexity. This session aims to address this gap by providing participants with insights and strategies to navigate these challenging cases.

2. Multidisciplinary Collaboration: The diagnosis of rare and undiagnosed diseases often requires a multidisciplinary approach. This session emphasizes the importance of collaboration in addressing diagnostic dilemmas.

3. Advanced Technologies and Innovative Methodologies: There is a need to bridge the gap between the availability of advanced technologies and innovative methodologies and their optimal utilization in practice. This session will highlight the application of these strategies by the UDN, addressing the gap in knowledge and awareness of these cutting-edge diagnostic tools.
