    Objectives Identifying genetic pathogenic variants improves clinical outcomes for children with developmental and epileptic encephalopathy (DEE) by directing therapy and enabling accurate reproductive and prognostic information for families. We aimed to explore the additional personal utility of receiving a genetic diagnosis for families. Methods Semi-structured interviews were conducted with fifteen families of children with a DEE who had received a genetic diagnosis. The interviews stimulated discussion focusing on the impact of receiving a genetic diagnosis for the family. Interview transcripts were analyzed using the six-step systematic process of interpretative phenomenological analysis (IPA). Results Three key themes were identified: “Importance of the label,” “Relief to end the diagnostic journey,” and “Factors that influence personal utility.” Families reported that receiving a genetic label improved their knowledge about the likely trajectory of the DEE, increased their hope for the future, and helped them communicate with others. The relief of finally having an answer for the cause of their child's DEE alleviated parental guilt and self-blame as well as helped families to process their grief and move forward. Delay in receipt of a genetic diagnosis diluted its psychological impact. Significance To date, the factors associated with the personal utility of a genetic diagnosis for DEEs have been under appreciated. This study demonstrates that identifying a genetic diagnosis for a child's DEE can be a psychological turning point for families. A genetic result has the potential to set these families on an adaptive path toward better quality of life through increased understanding, social connection, and support. Early access to genetic testing is important as it not only increases clinical utility, but also increases personal utility with early mitigation of family stress, trauma, and negative experiences.
