Özet: Smith-Magenis syndrome is a complex sporadically occurring neurodevelopmental disorder affecting many organ systems of the body, which is frequently observed 1/15.000-25.000. Haploinsufficiency caused by the RAI-1 gene at point 17p11.2 are responsible for the clinical manifestations in most of the patients. This syndrome has characterized by distinct craniofacial face appearance, delayed speech and speech difficulty, moderate to severe intellectual disability, behavioral problems and sleep disturbances. Particularly, behavioral problems and sleep disturbances are well defined and almost occur in every patient, gives an important clue about the diagnosis of Smith-Magenis syndrome if accompanied by dysmorphic features. In this study, we present a case with Smith-Magenis syndrome, which is followed by rare, non-typical findings and diagnosed by chromosomal microarray analysis.
