The study “Sacsin, mutated in ataxia ARSACS, regulates intermediate filament assembly and dynamics” has been published on October 23,2018 in the Federation of American Societies for Experimental Biology Journal (FASEBJ).“For the time being, this is a very interesting study that needs to be recognized by broad audience in life sciences and medicine” according to Dr. Robert Goldman an expert in the field of intermediate filaments and to the reviewers who have recognized the importance of publishing the data. This journal has a good reputation and a wide range of readership which should increase the awareness of ARSACS research.
In summary, the loss of Sacsin in the ataxia ARSACS leads to disorganization of the neurofilament network. This study identified direct roles of Sacsin domains in regulating intermediate filament assembly and dynamics, implicating Sacsin as an essential factor in maintaining cytoarchitecture.
For the first time, the public is invited to attend. The guest speakers at the Symposium will present their research in a “capsule” format from 8:30 to 9:30. Come meet our researchers, it’s free. Otherwise, you will be able to see the “capsules” on the website.
The research article of Dr. Anne McKinney and Dr. Alanna Watt entitled “Altered synaptic and firing properties of cerebellar Purkinje cells in a mouse model of ARSACS” has been published in the latest issue of the Journal of Physiology. See article
“Become an advocate, become involved, share advice, tell your story so that other parents with children with neurodegenerative disorders can learn from it. Above all, do not ever give up hope”. Interview with Mrs Brandi Brown, mother of a daughter with ARSACS.
The Foundation will fund Dr. Brais’ second research project for an amount of $80,000 in 2018-2019.
The aims of the project “Integrated Validation Pipeline for Candidate Drugs for ARSACS” are to validate candidate compounds in neurons and to combine genomics and proteomics strategies to pinpoint pathways affected by candidate drugs.

16 researchers will share close to $1M in funding this year to pursue research on ARSACS. A total of 12 research projects have been selected by the Foundation for 2018-2019 with the goal of finding a treatment for ARSACS. The Foundation would like to thank all the researchers for their application and congratulations to the selected researchers. Description of the projects.
Good news! The ARSACS research project “A comprehensive study of the natural history of ARSACS: An essential step towards clinical trial readiness and evidence-based interventions”. was selected by the Canadian Institutes of Health Research (CIHR)and gets funding for a total of $569,925 over a 4 year period. Congratulations to Dr. Cynthia Gagnon and the research team!
First in-depth study on the characteristics of speech and swallowing in ARSACS, highlighting the impact of these deficits for ARSACS. This research is conducted by Dr. Vogel and Dr. Synofzik from the Centre for Neurology and Hertie-Institute for Clinical Brain Research in Tübingen. This is the first part of the overall research project funded by the Foundation. The second part of the project will address the possible treatment(s).
“By officially grouping all ARSACS patients by age, sex, and especially geographic location, the foundation believes that large companies like Pfizer or Bayer will be more inclined to test new drugs.” . Article by Pierre-Alexandre Maltais, Journal de Québec ( French version only).
The IRIC HTS platform completed a screen of 16 000 molecules on a cell line engineered by Dr Brais’ team showing the characteristic vimentin bundling of ARSACS. This led to the identification of a set of potential candidate compounds, of which the two most promising lead to an almost complete disappearance of the bundling without signs of cellular toxicity. Medicinal chemistry efforts are presently focused on designing new molecules based on the identified active chemotype to improve the desired properties to be tested in a pre-clinical using the already existing transgenic mouse model to demonstrate efficacy. In parallel, Dr Brais’ team developed native assays to translate the molecules’ activity into more physiological systems which will shed light on the biology mechanisms of the disease and how the candidate drugs work.
Many thanks to the Club Richelieu for supporting the ARSACS research. On behalf of the Foundation, Mrs Nicole Fortin, a mother of a child affected by ARSACS and a volunteer at the Foundation, accepted a cheque of $1000 presented by Mr. Jean-François Dallaire, president of the Club Richelieu in Alma.
After serious reflection, the ARSACS Foundation is of the view that there is a need for an overall ARSACS patient registry. Such registry will be on an international basis and will include individuals diagnosed with ARSACS regardless of their country of residence. In addition to being an an essential tool to researchers, a patient registry will provide an idea of the market size which the Foundation believes is a crucial element when discussing drug development possibilities with pharmaceutical companies.
If you or a family member are affected with ARSACS, you will be invited to register. Your registration will contribute to the development of treatments for the disorder. Stay tuned for further details.
A new research has shown that a cheap non-invasive test could be used to diagnose ARSACS according to an article published recently in the Brain journal of neurology. See press release from UCL Faculty of Brain Sciences (London) and the complete research article .
“To people with ARSACS, do not to get discouraged, believe in yourself, go ahead even if it takes longer, anything is possible. It is often the mind the first barrier. In addition, I would tell parents to develop their children’autonomy as much as possible with their limitations. It will help them later”. Letter from Jean François Collard.
If you are a researcher interested in ARSACS, the Ataxia of Charlevoix-Saguenay Foundation provides you with a great funding opportunity. Grant application must be received at the latest by May 25, 2018. Application form
The screening of new molecules at the end of 2017 made it possible to identify other candidate molecules. The list goes on! Already a team from IRIC is investigating whether molecules can get to the brain. The teams of Dr. Brais, Dr. Watts and Dr. McKinney of McGill University are advancing in their validation of molecules on other models. Dr. Schwarz’s team at Harvard is also involved in the validation process.
The Foundation is very pleased to announce that Mrs. Julie E. Duchesne has joined its Board of Directors. Mrs. Duchesne, actuary, FSA, FCIA, Partner, has some 20 years of experience in the field of benefits consulting and team leadership. She is currently Health Business leader for Canada in group insurance practice at Mercer. She has also served on the board of CIFAR (Canadian Pension and Benefits Institute).
The study has developed an algorithm to facilitate and improve the diagnosis of recessive ataxias, including ARSACS. Dr. Gagnon’s research team and Dr. Brais provided data on the functional abilities of people with ARSACS. This was made possible thanks to the support of the Foundation via Emerging team, the data from the first phase of this important project. It should be noted that this prestigious medical journal lists only a limited number of people among the authors. As a result, the names Dr. Gagnon and Dr. Brais are included in the RADIAL Working Group. “A Recessive Ataxia Diagnosis Algorithm for the Next Generation Sequencing Era”
Congratulations Sarah and thank you to all the donors for their contribution to the cause.
