Interviews explored delivery setting, longitudinal clinical relationships, data reanalysis and recontact, consent, data stewardship, privacy, and the pediatric-to-adult transition. Analysis combined deductive domains with inductive coding, with attention to similarities and differences across stakeholder groups.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Participants in all five groups saw clinical value in lifelong genomic medicine, citing the relevance of genomic information at multiple life stages, the ability to requery the genome as circumstances change, and the capacity to act on evolving knowledge. A minority contested this value, favoring more targeted testing. Many participants viewed the model as inevitable and described operational precedent for many component activities, from reanalysis of decade-old data and reclassification pipelines to \u201csequence once, query often\u201d workflows and EHR-integrated alerts. Participants described substantial gaps in governance, spanning delivery setting, consent, data stewardship, recontact, and the pediatric-to-adult transition, alongside continuing operational challenges such as interoperability. No delivery setting was clearly favored: participants saw newborn screening as offering the strongest equity case but as conflicting with the explicit consent it would require, health-system delivery as excluding those without access, and commercial models as potentially short-lived. Participants raised equity concerns at enrollment, in maintaining follow-up, and at the pediatric-to-adult handoff, which we argue are cumulative and mutually reinforcing for those least connected to health systems.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Many participants expected lifelong genomic medicine to be implemented, but no comprehensive or clearly favored model for delivering it responsibly emerged.
