This website provides information on patients with mutations in the Phosphatidylinositol glycan class S (PIGS) gene, including clinical data, molecular data, management and research options.

The syndrome caused by mutations in the PIGS gene is called Developmental and epileptic encephalopathy 95 (DEE95) and is a multisystem disorder characterized by seizures, intellectual disability, coarse facial features, ataxia and hypotonia. Not all individuals with a mutation in the PIGS 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 PIGS gene.
