Among 411 neonates with PCHB, genetic disorders (27.2%, 112 of 411) were the leading aetiologies. There were 8 deceased neonates, 19 neonates with liver failure and 12 with neurodevelopmental delay. Among 528 neonates with PUCHB, a genetic aetiology was identified in 2 of 219 neonates (0.9%) who showed disappearance of jaundice within 4 weeks of age and in 32 of 309 neonates (10.4%) with persistent jaundice after 4 weeks of age. A total of 96 of 181 neonates (53.0%) who received genetic diagnoses had their clinical diagnosis modified as a result of the genetic diagnoses.Conclusion Known aetiologies were identified in approximately 80% of neonates in our cohort, and their overall outcomes were favourable. Genetic aetiology should be considered a priority in neonates with PCHB or the persistence of jaundice after 4 weeks of age. Moreover, genetic data can modify the clinical diagnosis and guide disease management, potentially improving outcomes.Data are available upon reasonable request.
