Spinocerebellar ataxia type 3, or Machado-Joseph disease (SCA3/MJD), is an autosomal dominant neurodegenerative disorder caused by a CAG expansion at ATXN3. The gene product is a 42kDa protein called ataxin-3, widely expressed in neurons and peripheral tissues. Physiological roles of ataxin-3
Spinocerebellar ataxia 3 (SCA3) is a rare form of inherited neurodegenerative disease involving progressive degeneration of spinocerebellar tract. SCA3 is characterised by increasingly worsening cerebellar function leading to gait abnormalities and poor coordination, dysarthria, and abnormal eye
Spinocerebellar ataxia type 3, also called Machado-Joseph disease (SCA3/MJD), is an autosomal dominant neurodegenerative disorder caused by a CAG expansion (CAGexp) on ATXN3. Over 20 years after the identification of the causal mutation, no form of prevention or treatment for this incapacitating
This prospective single arm interventional study involved 13 genetically confirmed spinocerebellar ataxia (SCA) 3 patients with no concomitant diabetes, over 6 months. Following baseline assessment, patients were instructed to ingest 100g of oral trehalose diluted in 500ml of water or other
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
Inherited cerebellar ataxias are genetically heterogeneous neurological disorders. They are characterized by ataxic gait and cerebellar dysarthria that progresses over time with loss of ambulation and speech. The mutations by expansions of CAG triplets in the genes ATXN1 (SCA1), ATXN 2 (SCA2), 3
Thirty individuals who have been diagnosed with either Spinocerebellar Ataxia - 1 (SCA1), Spinocerebellar Ataxia - 3 (SCA3), or Spinocerebellar Ataxia - 6 (SCA6) will be recruited for this study. Participants will be randomly assigned to a best medical management (BMM / control) group and an
Specifically, we would expect to see
1. Parkinsonism and other non-ataxia symptoms are more commonly present in SCA6 patients than we used to think.
2. Parkinsonism is associated with the loss of DAT in striatum.
3. Parkinsonism and other non-ataxia symptoms are also associated with the expanded
