Important and exciting recent developments in our understanding of bulk lipid transfer and NA syndromes were highlighted at the recent joint congress of German national societies (DGN) for neurology, neuropediatrics and neuropathology AKA "NeuroWeek.  Read on...

Chairs Kevin Peikert (left) and Adrian Danek (middle) discuss with Bernhard Landwehrmeyer (right) who introduced VPS13 related research in relation to future insights into Huntington’s Disease. At the joint congress of the German national societies for neurology (DGN), neuropediatrics and neuropathology, with more than 5000 participants (November 1st-5th, 2022), we organized a 90 minutes symposium dedicated to VPS13 research. Nine speakers reviewed “Recent developments in bulk lipid transfer and the so-called ’neuroacanthocytosis’ syndromes”.


Only quite recently, location and function of the members of a hitherto little-known protein family (VPS13 A through D) were unraveled. Located at contact sites of membranes of different cell organelles, these proteins act as conduits for non-vesicular lipid transfer. Deficiency of these proteins likely causes alterations of membrane lipid dynamics. The corresponding human genes lead to hereditary neurological disease, such as chorea-acanthocytosis (VPS13 A disease), Cohen syndrome (VPS13B disease), familial parkinsonism with Lewy bodies (VPS13C disease) or various ataxic conditions (VPS13D disease, earlier names: SCAR4, SCA24, or SCASI). Because of molecular interaction, the disease spectrum also involves McLeod syndrome (XK disease) and possibly other conditions.


The presenter team consisted of senior and junior clinical and basic scientists. Bernhard Landwehrmeyer from Ulm University by introduction highlighted possible connections with Huntington’s Disease (HD). While we subsequently presented a bench to bedside and vice versa approach to VPS13A and XK disease, our invited speakers covered additional aspects of the lipid dynamics at membrane contact sites in neurodegenerative diseases (D. Großmann, Rostock), Cohen syndrome (W. Seifert, Berlin) as well as clinical spectrum and treatment by deep brain stimulation in VPS13D-associated disease (N. Brüggemann and M. Pauly, Lübeck). Current experimental work from the Rostock group was covered by A. Spranger who presented lipidomics data from VPS13A disease red blood cells. At the final day of “Neuroweek” our session was mentioned in the movement disorders highlights session (B. Balint, Zurich) because of the importance of a novel pathomechanism that eventually may translate to more prevalent diseases such as Parkinson´s disease and HD.


We are grateful to the DGN scientific board for recognizing this future perspective by including our symposium in the program. The local audience, albeit small (approximately 50), was select and the hybrid format of the congress, including the availability of recordings, will allow for a much wider impact of our symposium.

Adrian Danek Presents New Insights on NA Syndromes
by Adrian Danek

Adrian Danek presented a highly instructive educational webinar on NA diseases on October 25, 2022. It is still available online.

For a number of years now, the European Reference Networks for Rare Neurological Diseases (ERN-RND) and Neuromuscular Diseases (ERN-EuroNMD) and the European Academy of Neurology (EAN) have organized freely accessible educational webinars on topics within their scope of interest (https://www.ern-rnd.eu/education-training/webinars/). For the second time, Adrian Danek, University of Munich (LMU), Munich, Germany, was invited to review the diseases of interest for the NA community and to present the most recent insights. In late October, he spoke on “VPS13A and XK bulk lipid transfer diseases (formerly the now obsolete Levine-Critchley syndrome)”, giving a clinical review on the diseases as well as presenting the recent breakthrough concerning the final diagnosis of patients first encountered in the 1960s in Boston.


Descendants of that family, originally studied by Irving Levine, had made contact with the NA patient advocacies and the group of researchers contributing to the GeneReviews® resource provided by the US National Center for Biotechnology Information (https://www.ncbi.nlm.nih.gov/books/NBK1354). It turned out that not only their family side branch carried a mutation in XK, the McLeod gene, but that also the index patient of Levine´s 1968 report was affected by exactly that condition. A quest of many years duration (see NA news issue 29 of 2017) was thus successfully completed (http://newsletter.naadvocacy.org/1ksy8liwtpm?a=2&p=52686232&t=16038454).


In summary, the further use of the term Levine-Critchley syndrome makes no sense, as the patients previously collected under this label have been proven to be affected by two distinct conditions: by VPS13A mutations in the case of Critchley´s Kentucky family (as shown in 2011) and by XK mutations in the New England family of Levine. Prof. Danek also pointed out why these two conditions are so similar and so easily mistaken for one another: most recent basic science research, including from his lab (Gabriel Miltenberger-Miltenyi in support of work in Aaron Neiman´s lab), demonstrated physical interaction of the two respective proteins, the scramblase XK and the lipid transfer “tube” VPS13A.


Likewise, use of the term “neuroacanthocytosis” in a scientific context makes no longer any sense as - in addition to cases affected by XK or VPS13A disease - also patients suffering from PKAN (pantothenate kinase associated neurodegeneration) have historically been grouped under that label. For advocacy work the label might be retained, but its heterogeneity must be kept in mind if one proceeds to discuss the situation of the individuals affected by the various underlying conditions.


Prof. Danek´s ERN-RND webinar is still available for viewing on https://www.youtube.com/watch?v=INjEk4oc_mY, as is his previous presentation https://www.youtube.com/watch?v=zbAIPsFhjms that covers more of the clinical information on the subject. His slides are available via https://www.ern-rnd.eu/education-training/past-webinars/.

Charity Manager Attends Conference
Mette Jolly attends Beacon Drug Repurposing for Rare Diseases Conference
by Mette Jolly

The Advocacy's new charity manager reports on her October attendance at the Beacon Repurposing for Rare Diseases Conference.

Tower of LondonOn Monday 10th October Mette was pleased to attend the Beacon Drug Repurposing for Rare Diseases Conference at America Square near the Tower of London.



Drug repurposing is the process of identifying new uses for medicines that are outside of the scope of their existing licence, in other words taking an existing drug and using it to treat a different disease from the one it was originally developed to target. Drug repurposing can contribute to lowering the costs and accelerating the development of rare disease treatments.



At the meeting in London, 150 delegates from advocacy groups, bio science companies, academia and umbrella organisations gathered to exchange research and experiences. Expert speakers from the UK and beyond highlighted major projects driving repurposing across the UK and Europe.



Presentations also included patient stories and the introduction of new resources (see links below) A particular highlight was an example of a patient group working with scientists and a non-profit biosciences company on recruiting for a clinical trial.



The overall conclusion of the day was positive with consensus being that drug repurposing, which has had a difficult start, is becoming increasingly mainstream.

Trustees Meet Patients Around the World
Travel plans include visits to patients and their families
by Candi DiMarzio and Joy Willard-Williford

Candi DiMarzio, a board member of NA-USA, files this report on her visit to ChAc patient Mike Koutis in Canada.

Mike Koutis befriended me on Facebook over 5 years ago. Somehow through the grapevine someone gave Mike my name. The rest is history.



Mike has a hard time sleeping and so do I. I would get an alert that I received a message on my phone anytime from midnight on and it would be Mike. We would chat for an hour or so. After a year or so Mike said he would like to have his friend message me if that was ok. He said “you will love her.” That friend was Kristy Santangelo Mohr.


Soon after interacting with Kristy, Mike went into cardiac arrest and was unresponsive. Kristy notified me right away to tell me about Mike. He was in ICU for about 2 weeks. During those 2 weeks Kristy was Mike’s patient advocate. She was so effective that now everyone that knows Mike knows Kristy. I started sending Mike a card every week after he got back to the nursing home and that has continued for over 4 years. 

Kristy would call me on Messenger when she was visiting Mike and we got to communicate.



Soon after my daughter Heidi passed away Mike’s brother Kerry passed away from ChAc. I asked Mike what his mothers name and address was because I wanted to send her a card. Soon after Mrs. Koutis received my card she called me. Our friendship started to build from there.


I kept telling Mike that someday I was coming  to Canada to personally meet him. Then COVID came. In the summer of 2021 the border was reopened between the US and Canada. My only prerequisite was I had to come in the summer as I could not manage the frigid Canadian winter. My trip was planned to go to Winnipeg, Manitoba Canada on July 20th, 2022. When I landed in Winnipeg I thought to myself this is going to be odd not ever meeting Kristy. I was getting my luggage and turned around and there stood Kristy. She was everything I thought she would be and more.



Walking into Mike’s nursing home room was a moment I will never ever forget. We both started crying and held onto each other tightly. While I was there Kristy asked me if there was anything in particular I would like to do after seeing Mike. I told her I wanted to meet her family, her mother and Mike’s mother. I wanted to be sure to let her mother know what a terrific daughter she raised. Needless to say my goodbye was very very difficult.



Mike was everything I thought he would be and more. I hope to be able to go see Mike again. Mike and Kristy are now family. This was a vacation I will never ever forget.



Candi wasn't the only board member on the move. Check out our gallery below for more adventures in travel for patients and trustees.

Save the Date - Upcoming 11th International Meeting on Neuroacanthocytosis Syndromes
by Kevin Peikert and Lars Kaestner

Prof. Lars KaestnerGrab your calendars! You won't want to miss the 11th International Meeting on Neuroacanthocytosis Syndromes in Homburg, Germany, September 15-17, 2023, organized and chaired by Lars Kaestner of the Saarland University.

Meeting venue: University of Saarland campus in Homburg, GermanyAs an international community of clinicians, scientists, and families dealing with chorea-acanthocytosis (VPS13A disease) or McLeod syndrome (XK disease), respectively, we had enjoyed the virtual “Barcelona” symposium in 2021.


But now, it is urgently time to meet again in person! To continue our conversation at “on-site” meetings, the last of which was held in Dresden, Germany more than four years (!) ago, we are pleased to announce that we are currently planning the 11th International Meeting on Neuroacanthocytosis Syndromes as an in-person meeting at the Saarland University in Homburg, Germany, September 15 - 17, 2023.


The symposium will be organized and chaired by Prof. Lars Kaestner. More details will follow soon.
