What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

Parkinson's disease (PD) is an age-related movement disorder with a complex pathophysiology. Among the risk factors for PD, variants in beta-glucocerebrosidase (encoded by the gene GBA1) represent one of the most significant heritable risk factors for lifetime PD risk. Biallelic variants in GBA1 cause Gaucher disease (GD), a multisystem disorder, and individuals with late/adult-onset GD1 have a \~1-in-9 lifetime risk for PD. This study aims to develop a cross-sectional cohort of clinical and laboratory phenotyped adult GD1 patients and controls for investigation of clinical/laboratory risk factors for current and future Parkinson risk. Neurological evaluations will be video and audio recorded to allow the investigators to quantify neurological function using automated tools. Data and specimens generated in this study will be incorporated into a de-identified biobank that will be used for further research into GD and PD.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Type 1 Gaucher Disease patients currently receiving their care at the Mount Sinai Health System or partnering Gaucher Disease treatment programs will be screened for eligibility. GBA1 carrier and non-carrier participants will be recruited from the interested relatives of our GD patients. It is expected most of our participants live in the northeast United States, speak fluent English, and are of Ashkenazi Jewish ancestry as there is a higher prevalence of GD in this ethnic group.

Ages

40 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
