A study on the Rett syndrome in the GDR

Of 44 subjects identified by the screening procedure, 31 were enrolled in the study. Using the modified Vienna Rett score, we divided the patients into three groups: typical the Rett syndrome (RS) (n = 10), incomplete forms of RS (n = 5) and non-RS (n = 16). Genetic investigations were performed in some cases and abnormalities were found in two. EEG and cranial computerized tomography findings are discussed.
