Whole exome sequencing (WES) is a relatively new testing option, currently offered primarily in the pediatric setting, that is open to more uncertainty than single gene or gene panel testing. This uncertainty makes pre-test counseling challenging yet critical to ensure informed consent. Adaptation of counseling strategies for this type of testing requires a better understanding of parents' experiences throughout the WES testing process. However, the experience of parents of chronically ill children who have actually gone through the entire WES testing process has not been widely reported in the literature. Currently, analysis of exome test results at Children’s Hospital of Pittsburgh does not include the incidental findings that are typically reported in WES results (i.e. variants in genes that are not associated with the child’s present condition) and is, therefore, referred to as “targeted exome sequencing” (TES). This study was designed to gain an understanding of the psychosocial impact on parents of the TES testing process for chronically ill children in order to improve test education, consent and results disclosure processes and to better help parents cope with the results. Semi-structured interviews were conducted with 11 parents of children who received targeted exome sequencing results and thematic analysis was performed on transcripts generated from the interviews. The experiences and opinions of parents whose children received positive, likely negative or uncertain results were analyzed, in order to develop a robust understanding of the full TES process. This study has Public Health significance because the results may contribute to the development of updated recommendations for optimizing informed consent and results disclosure for TES.
