Official Title: Synergistic Enteral Regimen for Treatment of the Gangliosidoses (Syner-G)
Brief Summary: The investigators hypothesize that a combination therapy using miglustat and the ketogenic diet for infantile and juvenile patients with gangliosidoses will create a synergy that 1) improves overall survival for patients with infantile or juvenile gangliosidoses, and 2) improves neurodevelopmental clinical outcomes of therapy, compared to data reported in previous natural history studies. The ketogenic diet is indicated for management of seizures in patients with seizure disorders. In this study, the ketogenic diet will be used to minimize or prevent gastrointestinal side-effects of miglustat. A Sandhoff disease mouse study has shown that the ketogenic diet may also improve central nervous system response to miglustat therapy (see Denny in "Citations" list below). Patients with infantile and juvenile gangliosidoses commonly suffer from seizure disorders, and use of the ketogenic diet in these patients may therefore also improve seizure management.
