Abstract
AbstractThis report highlights a rare single-gene cause of early-onset, treatment-resistant schizophrenia, and its unique responsiveness to clozapine therapy. This case describes a pediatric female who was diagnosed with early-onset schizophrenia and catatonia in her early adolescence, and was later found to have DLG4-related synaptopathy, also known as SHINE syndrome. SHINE syndrome is a rare neurodevelopmental disorder caused by dysfunction of the postsynaptic density protein-95 (PSD-95), encoded by the DLG4 gene. After failing three antipsychotic drug treatments, the patient was started on clozapine, which resulted in significant improvements in positive and negative symptoms. This case illustrates the impact of clozapine in treatment-resistant early-onset psychosis and exemplifies practical implications for genetic testing in early-onset schizophrenia.
