Major clinical improvement in a boy with developmental disabilities and a PTPN4 mutation with intensive re-education and an enriched environment in a day care hospital: a case report

Despite a severe communication disorder associated with sensory integration issues, anxiety, and elimination disorder, a diagnosis of autism spectrum disorder was ruled out, and remarkable progress was observed, which allowed our patient to attend same-age mainstream schools with personalized support at discharge. This case illustrates the effect of dimensional interventions to limit developmental impairments in a context of PTPN4 mutation and the benefit of providing an enriched environment in combination with individual re-education to improve developmental outcomes.
