This website provides information on patients with mutations in the SMS gene, including clinical data, molecular data, management and research options.

The syndrome caused by mutations in the SMS gene (Snyder Robinson syndrome, OMIM # 309583) is an X-linked intellectual disability syndrome characterized by hypotonia, general asthenia, global developmental delays/intellectual disability, seizures, unsteady gait, dysarthric speech, osteoporosis, and kyphoscoliosis. Not all individuals with a mutation in the SMS gene have these features.

This website was created to share and collect information about clinic, management and research projects to gather more knowledge and provide better treatment of patients with mutations in the SMS gene.
