The study consists of two sequential cohorts with a total of approximately 20 patients enrolled. Patients in each cohort may participate for up to 4 weeks. Each participant will have up to 2 Emerald devices installed in their home for monitoring sleep, breathing and movement, and will use between 3 and 9 nPoint patches for determining proper patch placement for detecting breathing signals.~The study will consist of a Screening visit, an Observation period, and a Follow-up phone call. The Screening Period will be one day in clinic, the Observation period will be up to 4 weeks at home and the Follow up phone call will be performed at the completion of the Observation Period.
This is a pilot study of the Emerald device in Rett syndrome patients diagnosed with a confirmed MECP2 mutation. MC10 BioStamp nPoint patches will also be assessed with the goal to develop Rett-specific breathing algorithms
