Brief Summary:
The purpose of this study is to examine the differences in cerebral spinal fluid (CSF) and blood of patients with spinocerebellar ataxias and healthy volunteers. The goal of this project is to identify new biomarkers that are useful for characterizing spinocerebellar ataxias and identify targets for treatment or prevention of this condition.

Condition or disease Intervention/treatment
Spinocerebellar Ataxia Type 3 Other: Specimen Collection

Detailed Description:

Participants will undergo a SARA exam, a lumbar puncture and a blood draw. A lumbar puncture is a procedure in which a small amount of the spinal fluid that surrounds the brain and spinal cord is removed by inserting a needle in the lower back. Participants will be asked not to eat or drink anything (water is acceptable) for at least 6 hours before the lumbar puncture visit. For this procedure, participants will be positioned lying on their side and curled up in a ball, or sitting up and bent forward, whichever is easier. Cushions will be used to enhance comfort. The lower back region will be cleaned and disinfected with an antiseptic iodine solution. The doctor will inject local anesthetic (lidocaine, 1%) into the skin of the lower back. This may produce a transient, mild burning sensation. A very small needle will be introduced into the skin and moved into fluid-filled space around the spinal nerves coming from the spinal cord. This may produce a pressure sensation. Approximately 2 tablespoons approximately 30 ml) of fluid will be collected. The needle will be removed and a band-aid applied over the needle insertion site. Participants will be asked to remain stationary, lying on flat for about ½ hour on a bed in the research clinic. Participants will be given something to eat and drink before leaving. Strenuous physical activity should be avoided for the next 24 hours. This includes lifting, bending, doing housework and gardening, or doing exercise such as jogging or bicycle riding. The SARA (Scale for the Assessment and Rating of Ataxia) exam is a clinical scale that assesses a range of different impairments in cerebellar ataxia. The scale is made up of 8 items related to gait, stance, sitting, speech, fingerchase test, nose-finger test, fast alternating movements and heel-shin test, and takes approximately 15 minutes to complete.

The study also involves a single collection of about 3.5 tablespoons (approximately 50 ml) of blood. This blood draw may take place during a regularly scheduled visit to the neurology clinic or at the research appointment.

Group/Cohort Intervention/treatment
Affected Individuals with Known SCA3
In order to be eligible for this cohort, participants must have confirmed genetic testing results for Spinocerebellar Ataxia Type 3.
Other: Specimen Collection
No interventions take place as part of study participation- only specimen collection occurs for both cohorts.

Healthy Individual Control Subjects
In order to be eligible for this cohort, subjects must not have a diagnosis of Spinocerebellar Ataxia Type 3 and no major medical issues including but not limited to conditions that would cause an unsafe specimen collection.
Other: Specimen Collection
No interventions take place as part of study participation- only specimen collection occurs for both cohorts.




Primary Outcome Measures :
  1. Change in Ataxin 3 Levels in Cerebrospinal Fluid Specimens [ Time Frame: 4 Hours ]
    A lumbar puncture is performed to collect CSF.

  2. Change in Ataxin 3 Levels in Blood Plasma Specimens [ Time Frame: 4 Hours ]
    A single blood draw is completed.


Biospecimen Retention:   Samples With DNA
Approximately 2 tablespoons (approximately 30 ml) of CSF will be collected, along with a single collection of about 3.5 tablespoons (approximately 50 ml) of blood.
