Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This protocol is a screening and natural history protocol, which allows for evaluation of

patients and families where neurological conditions are present for enrollment into other

studies and will also be used to screen healthy volunteers to create a pool of potential future HV matches for HMCS protocols. Through diagnostic evaluations, data will be collected for research use in this study.
