Genetic Testing in the Pediatric Nephrology Clinic: Understanding Families' Experiences

Genomics is rapidly being integrated into the routine care of children and families living with renal disease, principally as a diagnostic tool but also to direct therapy, identify at-risk relatives, and facilitate family planning. However, despite significant progress in understanding the genetic heterogeneity of inherited renal disease, the impact of genetic testing on parents and families of affected children is not well understood. This study aimed to investigate the experiences of families undergoing genetic testing, the psychosocial impact of receiving a genetic test result, and parent information and support needs. In-depth semistructured interviews were conducted with 26 parents of pediatric patients (<18 years of age) who had undergone genomic investigation for a suspected genetic renal disease at two tertiary pediatric nephrology services. Interviews were transcribed verbatim, coded, using NVivo software, and thematic analysis was undertaken. Key themes included emotional adjustment to a genetic diagnosis, the importance of parent-provider relationships, empowerment through social connection, and the value of family-centered care. Results highlighted the wide-ranging psychosocial impact of genetic testing on parents, as well as the importance of patient-support networks in enabling parents/families to cope and adapt. Targeted approaches to enhance communication of genetic information and the development of tailored resources to address parents' genetics and health service needs may lead to more satisfactory experiences of genetic testing.
