Spinocerebellar ataxia type 6 SCA6 is a rare hereditary movement disorder affecting 5 of every , people worldwide 1. The length of this repeat, which is made up of sequential iterations of the code CAG, is normally variable in length, stretching between 4 and 18 repeats in the healthy population. However, in SCA6 patients, something goes wrong and the CAG repeat in the CACNA1A gene is expanded to have repeats, causing dysfunction in the brain and motor symptoms for reasons that are not yet fully understood.

Federal government websites often end in. The site is secure. Spinocerebellar ataxias SCA are a group of rare neurodegenerative diseases that dramatically affect the lives of affected individuals and their families. Research efforts have greatly expanded the possibilities for potential treatments, including both pharmacological and non-pharmacological interventions. Great attention is also being given to novel therapeutics based in gene therapy, neurostimulation, and molecular targeting. This review article will address the current advances in the treatment of SCA and what potential interventions are on the horizon. SCA is a highly complex and multifaceted disease family with the majority of research emphasizing symptomatic pharmacologic therapies. As pre-clinical trials for SCA and clinical trials for other neurodegenerative conditions illuminate the efficacy of disease modifying therapies such as AAV-mediated gene therapy and ASOs, the potential for addressing SCA at the pre-symptomatic stage is increasingly promising. Spinocerebellar ataxias SCAs are autosomal dominantly inherited, progressive neurodegenerative disorders marked by cerebellar degeneration[ 1 ]. SCAs are numbered in the order in which they were chronologically identified, with over 40 of them being genetically and phenotypically characterized Table 1 [ 2 ].

Early-bird discount available for a limited time. Pastor and colleagues identify FDA-approved small molecules that selectively reduce the toxic polyglutamine-expanded protein in SCA6. Selectively targeting disease-causing genes without disrupting cellular functions is essential for successful therapy development. In spinocerebellar ataxia type 6 SCA6 , achieving this selectivity is particularly complicated as the disease-causing gene produces two proteins that contain an expanded polyglutamine tract. In this study, Pastor and colleagues identified several Food and Drug Administration FDA approved small molecules that selectively reduce the levels of one of these polyglutamine-containing proteins without affecting the levels of the other protein, which is essential for normal brain function. By using drugs already approved by the United States Food and Drug Administration to treat other diseases, referred to as FDA-approved drugs, the team hopes to reduce the time frame for pre-clinical therapy development. SCA6 is an autosomal dominant ataxia that causes progressive impairment of movement and coordination.

Mild-to-moderate side effects included dizziness and gastrointestinal issues. The mean age of onset is between 43 and 52 years. Contribute Today. Cerebellum Ataxias. Clinically they have a coarse gaze-evoked nystagmus, downbeat nystagmus on lateral gaze Uueno et al, , and poor visual suppression Gomez et al, Heterozygous individuals. SCA6 belongs to the group of disorders called polyglutamine diseases, all of which are caused by CAG expansions in different genes. Formal neuropsychological testing in one series revealed no significant cognitive deficits [ Globas et al ]. Occupational and physical therapy are of utmost importance in SCA patients to treat debilitating symptoms and increase quality of life; speech therapy is also critical, as dysphagia may lead to aspiration. J Neurol Sci. Episodic Ataxia. To screen the FDA-approved drugs, the group developed a system to easily measure the levels of a luminescent reporter protein produced by IRES-mediated translation.

According to Diallo et al , " The year survival rate was The publisher's final edited version of this article is available at Expert Rev Neurother. Clinical evaluation of eye movements in spinocerebellar ataxias: a prospective multicenter study. Protein: A molecule determined by a specific sequence of DNA. In this GeneReview. This research focuses on drug discovery against ATXN3 using phytochemicals of different plants. The site is secure. It is also interesting to consider the presence of somatic mosaicism in HD and SCA, which is observed prominently in the central nervous system and is linked to DNA repair mechanisms [ , ]. Importantly, allogeneic cells were preferred over autologous cells due to their resilience against potential ineffectiveness arising from underlying genetic issues Sleep apnea. Make a Donation.
