The aim of this retrospective, multicenter study would be to extend the phenotypic spectrum of DeSanto Shinawi Syndrome and improve the knowledge of its evolution. To this end, the investigators would like to issue a call for international collaboration in order to create a series of new genetically diagnosed patients, not yet described in previous publications, and with a larger number of individuals evaluated in a single study. One of the aims would be to establish a set of standardized clinical and paraclinical examinations to be carried out at diagnosis and for follow-up of affected patients. This would enable patients, their families and the caregivers involved to better anticipate future management.
