Objective To identify the clinical characteristics and investigate function related aspects of Korean children with Rett syndrome. Method A total of 26 patients diagnosed as Rett syndrome were clinically observed until the age of fi ve or over. We surveyed past history, developmental history, and presence of typical clinical features of Rett syndrome. Furthermore, we investigated diff erences in clinical characteristics according to functional status and changes in clinical features related to growth. Results There were no problems related to gestational, perinatal or neonatal history. Only 12 patients had an ultimate head circumference of less than 3 percentile. Developmental regression was definite in all patients. At final assessment, only 14 patients were able to walk. Twenty patients had an epileptic history requiring medication. Sixteen patients with scoliosis showed progression during serial follow-up. Th e percentage of patients who were able to walk before 16 months was higher in the high function group than the low function group. Th e age of regression was 5.4 and 4.0 years in the high and low function group respectively, but the diff erence was not statistically signifi cant. Scoliosis was more severe and seizure onset age was younger in the low function group. Conclusion We investigated 26 clinical characteristics in Korean children with Rett syndrome. Their clinical features change according to age, and we believe such knowledge could be utilized in rehabilitation to minimize their disabilities.
