Rett syndrome was described in 1966 and became known through the English medical literature in 1983. There are typical and atypical forms. The objective of this study was to record the cases diagnosed in Spain and discover their clinical characteristics in order to describe its phenotype and geographical distribution. We know of 207 cases and have obtained the records of 168 of these patients. A protocol and data collection programme has been developed giving the criteria for inclusion, and data which support or exclude this. Data collection was by post and the data for identification were the date of birth and the initials of the name and two surnames. With these variables, double-registering of patients was almost impossible. A statistical study with descriptive analysis and a study of continuous and alternating variables was immediately done. The results gave the main characteristics, the differences between typical and atypical cases and a comparative study of variables. It has given clinical data which may be useful for prognosis of the condition in the future.
