In addition, each chapter includes pertinent cases from Peay's and Austin's experience in genetic counseling. The cases bring each chapter's discussion around a particular topic to a conclusion, often including family history and the graphic pedigree. In Chapter 8 and Chapter 9, the cases focus on the subject of pregnancy and parents of at-risk children and affected children. One case involves parents who are both physicians and have an autistic child; they are expecting a second child. The authors explain how the clinician could address the parents' questions about the etiology of autism and a conversation about how the parents might manage the uncertainty regarding the baby's condition for the remainder of the pregnancy and early in the baby's life. Other chapters include cases about unaffected family members, genetic susceptibility testing, and genetic testing to inform medication strategy.
