FOLLOW US ON BLUESKY

You can now find us on BlueSky @ern-rnd.bsky.social as we will be leaving X soon.

BlueSky looks and functions pretty much like twitter - have you noticed? This is because it was conceptualized by former Twitter CEO Jack Dorsey in 2019 and developed in parallel with twitter. So moving from X to BlueSky is very easy, as everything is familiar - and it's even in the same blue colour as twitter was!

So: Try it out and follow us to BlueSky. We hope to see you there soon!

Also on BlueSky: ERDERA, The European Commission, ERN eUROGEN, ERN VASCERN, ERKNet, EFNA, EURORDIS, ESHG - add us all, many more will follow!

1) Solve-RD: The Worth of Reanalysis
Within the Solve-RD project, over 300 experts from different European countries and Canada re-analysed genome data from undiagnosed 6447 patients. They were able to diagnose 506 patients and their families. For 15% of the patients, there are leads for actionability, in some including treatment; in other cases, the diagnosis provides clarity for the patients and their families (press release).

Solve-RD and ERN-RND coordinator Holm Graessner is giving some insights into the project and talks about future steps in our video interview:

2) NGS: European Quality Assessment for ERN-RND Centers
Why is a quality assessment on European level important for next generation sequencing (NGS)? What needs to be improved and what’s the benefit of having a network of expert centers like ERN-RND to work with?

Ales Maver, clinical laboratory scientist at the University Medical Center in Ljubljana, talks about the insights and outcomes of the quality assessment for NGS that was done within the ERN-RND network 2024 in this video:

DISEASE KNOWLEDGE

In order to reach as many patients, clinicians and carers as possible we are systematically translating our patient journeys into different languages.

The patient journey for Huntington's Disease is now available in 15 languages, so that we are starting our official patient journey dissemination with this disease - with the other disease groups to follow soon.

Our ePAG Astri Arnesen is sharing her experience with doctors in the past and shows why a patient journey for Huntington's Disease is needed in this short video - please feel free to share (LinkedIn, Facebook, BlueSky):

CROSS-BORDER HEALTH CARE

MLD Treatment Eligibility Panel
In cooperation with the MLD initiative, ERN-RND established a standard pathway for consulting an international MLD expert panel whenever possible benefits of treatment with hematopoietic stem cell transplantation or gene therapy are not straightforward for a patient with confirmed MLD diagnosis. Upon submission of an eligible case, the treatment eligibility panel is convened on an ad hoc basis, organized and supported by the ERN-RND CPMS helpdesk.

We encourage all physicians in Europe to discuss the possible benefits of treatment options for difficult cases with this MLD expert panel.

You would like to discuss one of your patients with the panel?

Please contact us.
Neuroradiology Expert Advice for Diagnostic and Management Decisions in RND

ERN-RND has established a standard pathway for providing expert neuroradiological advice across sites.
Our ERN-RND member hospitals (and affiliated partners) are encouraged to contact us for any RND case for which they would like a second opinion as a basis for individual recommendations for diagnostic and management strategies to optimize patient care.

Possible scenarios for which clinicians might want to use this offer include (but are not limited to):
  • Child with mild developmental delay: benign / onset of disease? -> cMRI: delayed brain maturation vs. (subtle) structural abnormalities
  • Child with delay + subtle signs: acquired / genetic? -> cMRI: acquired disease, e.g. CMV infection / TORCH vs. likely genetic
  • Acutely ill patients with suspected encephalopathy -> cMRI: secondary, e.g. infectious / para-infectious vs. metabolic / genetic
  • Cerebellar syndrome with fast progression -> cMRI: secondary, e.g., cerebellitis vs. genetic
  • Patient after pharmacological treatment showing brain volume reduction -> cMRI: side effects vs. neurodegenerative / neurogenetic disease

To make use of this opportunity, imaging data must be provided via CPMS. Advice will be provided in a virtual meeting between the referring physician plus the initial neuroradiologist and a dedicated ERN-RND neuroradiological expert clinician (and further experts if necessary. Meetings are facilitated by the ERN-RND CPMS helpdesk.


You are affiliated to an ERN-RND expert center and would like to receive neuroradiology advice for one of your patients?
Please
contact us.
Online Multidisciplinary Board for Deep Brain Stimulation in Dystonia
ERN-RND has established a standard pathway for providing multidisciplinary expert recommendations concerning Deep Brain Stimulation (DBS) in Dystonia.

Potential questions which the multidisciplinary board may address include (but are not limited to):

    1. INDICATION DBS candidate yes/no?
    2. TARGET Which Target; GPi, STN, VoA?
    3. PROGRAMMING Treatment advices of implanted patients
To make use of this opportunity, relevant medical data must be provided via the telemedicine platform CPMS beforehand.
Advice will be provided by at minimum one dystonia expert specialized in DBS and a stereotactic surgeon specialized in DBS, plus further specialists invited case-by-case in a virtual meeting with the referring clinician.
Meetings are facilitated by the ERN-RND CPMS helpdesk.
NEXT ONLINE MULTIDISCIPLINARY BOARD MEETING (DBS IN DYSTONIA):
Thursday, 20/03/2025, 4 – 5 PM CET (Amsterdam/Berlin/Rome)

Case submission is possible until 03.03.2025

NATIONAL WORKSHOP
ON CROSS-BORDER HEALTHCARE (FRANCE
)

The registration for the next national workshop on the Cross-Border Healthcare Directive by the European Commission is now open. It is hosted by France in Strasbourg on 27 February 2025 within the premises of the European Parliament and will be held in French.
Find the agenda here.

PARTICIPATION CALLS

Joint Transnational Call
ERDERA Joint Transnational Call (JTC) 2025 invites innovative research proposals focusing on “Pre-clinical therapy studies for rare diseases using small molecules and biologicals – development and validation.”

This call aims to foster international collaborations to advance therapeutic solutions for rare diseases, benefiting millions of patients worldwide.

Projects should address at least two of the following:
  • Development of novel therapies in a pre-clinical setting.
  • Creation and validation of predictive and pharmacodynamic biomarkers.
  • Replication of pre-clinical findings to enhance reliability.
  • Pre-clinical proof-of-concept studies for therapy readiness.
Submission deadline February 13. Find more information here.
Call for Collaborative Genetic Research on Rare and Complex Epilepsies
The main aim of this initiative is to recruit cohorts of patients carrying rare variants in genes without a well-defined phenotypic spectrum, where single centre studies would not yield significant series.

EpiCARE can facilitate this type of studies by connecting several centers across Europe involved in the study of genetic epilepsies. Participation is not limited to EpiCARE members, it’s open to everyone.
