Release Date: 4/25/22
Expiration Date:  4/24/25

Target Audience: All physicians

Learning Objectives:

As a result of participation in this activity, participants should be able to:

  1. Recognize that a significant percentage (30-40%) of individuals with autism and related neurodevelopmental disorders (NDD) have an underlying rare genetic disease that can be identified by routine clinical genetic testing (microarray, exome sequencing, genome sequencing).
  2. Describe the value of identifying a specific genetic cause of a child’s NDD, including ending the diagnostic odyssey, establishing accurate recurrence risk for parents, informing prognosis and often directly impacting medical and educational management plans.
  3. Differentiate between the genetic concepts of incomplete penetrance and clinical variability as it applies to dimensional (quantitative) traits such as cognitive ability (e.g., IQ) and social behavior (e.g., SRS).
  4. Recognize the role of both rare genomic variants with large effect size and common genomic variants with individually small effect sizes but cumulatively large effects, as well as the interplay of these two classes of genomic variants (largely additive).

 

Requirements for successful completion: Certificates are awarded upon successful completion (80% proficiency) of the post-test.

Accreditation: The University of Florida College of Medicine is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians.

Credit: The University of Florida College of Medicine designates this enduring material for a maximum of 1 AMA PRA Category 1 Credit™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
