Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations b The behavioral phenotype, including significant sleep disturbance, stereotypies, and maladaptive and self-injurious behaviors, is generally not recognized until age 18 months or older and continues to change until adulthood Smith-Magenis Syndrome (SMS) is a rare neurobehavioral disorder characterized by a recognizable pattern of physical, behavioral, and developmental features. It is caused by particular genetic changes on chromosomal region 17p11.2, which contains the gene RAI1 .2 of chromosome 17 (Greenberg et al., 1991). Dysmorphic features in SMS include brachycephaly, broad nasal bridge, posteriorly rotated or low-set ears, prognathism, and brachydactyly
