NCT00001215

Brief Summary

The purpose of this study is to identify genetic, biochemical, and clinical factors that are associated with disease severity in people with Gaucher disease and other lysosomal storage disorders. There is a vast spectrum of clinical manifestations in people with Gaucher disease as well as other lysosomal storage disorders. This study will evaluate patients with lysosomal disorders on an outpatient or inpatient basis in order to better characterize the clinical, genetic, and pathophysiological features of these disorders. Participants will be re-evaluated on an annual basis.

Outcome Measures

Primary Outcomes (1)

  • Clinical Phenotypes

    The purpose of this study is to clearly describe the clinical phenotypes of individuals with lysosomal storage diseases in order to better understand the pathophysiology of these disorders and to develop new therapies.

    ongoing

Secondary Outcomes (1)

  • development of Parkinsonism

    ongoing

Study Arms (3)

Control

healthy volunteers

Family Member

a family member of a documented proband

Patient

the participant on initial screening must be found to have or be a carrier of a documented lysosomal storage disorder

Eligibility Criteria

Age1 Month+
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patient (or family members of patient) must be found to have or be a carrier of a documented lysosomal storage disorder.@@@

You may not qualify if:

  • These are generally pan-ethnic disorders. Efforts will be made to include any patient from an under-represented minority with these disorders.
  • Family members eligible/recruited include adult obligate carrier relatives, parents and siblings of Gaucher disease probands, and/or any relative with and without parkinsonism, where noncarriers volunteer for participation to serve as controls.
  • Eligibility criteria for healthy and PD control group participants include healthy participants recruited from the Healthy volunteers office or healthy non-mutation carriers family members who voluntarily agree to participate. Patients with Parkinson disease who do not carry GBA1 mutations are eligible to participate to serve as controls
