Introduction: Schaaf-Yang syndrome (SYS) is a rare autosomal dominant disorder, first identified in 2013, resulting from mutations in the paternal allele of the MAGEL2 gene. Schaaf-Yang syndrome exhibits clinical features similar to those of Prader-Willi syndrome (PWS), including hypotonia, joint contractures, developmental delay, and intellectual disability. However, SYS is also characterized by unique manifestations, such as recurrent hyperthermia, feeding difficulties, respiratory distress, and seizures. This case report describes the first SYS case identified in Iran. Conclusions: This case emphasizes the importance of considering SYS in patients presenting with unexplained fever, seizures, and neurodevelopmental delays. Early genetic testing is crucial for diagnosing SYS and differentiating it from conditions such as PWS or infection-related disorders. Timely diagnosis can improve management strategies and help reduce the risk of lasting neurological impairments associated with this genetic disorder.
