2nd International CTNNB1 syndrome Conference!


Welcome to our 2nd CTNNB1 syndrome conference!

Thank you for joining our flight to improve the lives of patients affected by CTNNB1 Syndrome.
Ljubljana was awarded European Best Destination 2022. Join our 2nd CTNNB1 syndrome conference and find out why!

We are pleased to invite you to our 2nd CTNNB1 Syndrome conference & clinical examination of children. The conference will be on 14th and 15th of June and the clinical examination of children on 15th and 16th of June 2024. Your presence will be invaluable as we come together to improve the lives of all patients affected with CTNNB1 Syndrome. This event marks an important milestone for our community as we recently successfully completed preclinical studies and have initiated our manufacturing process. Over the conference days, we have put together a program with the main focus on the gene replacement therapy, clinical readiness and updates on other treatment solution programs. As many of the symptom-related topics were already covered last year, this year we want to focus particularly on the rarer of the rare, including heart defects and epilepsy.

We look forward to the opportunity to catch up with familiar faces, give you a warm hug and listen to your experiences. Together, we will continue to drive progress and foster a supportive community committed to making a positive impact on the lives of those affected by CTNNB1 syndrome.

Join us on this journey of knowledge, connection and empowerment. Together we can make a difference!


The Dragonfly Study

The CTNNB1 Foundation is pleased to announce the first Natural History Study (NHS). This important research project aims to monitor the development of children and adolescents diagnosed with CTNNB1 syndrome.

You can read more about the study here.

The clinical assessments of these children will take place on 15 and 16 June in Slovenia. During these two days, dedicated medical professionals, including doctors and physiotherapists, will perform a series of examinations that include motor functions, neurological examinations, EEGs and blood tests. We are very grateful to the hospital and medical professionals who have volunteered their time and expertise to ensure that there is no additional financial burden on patients.

The deadline for submission of the application for the study has been completed. We thank everyone who decided to participate and are looking forward to seeing them in Slovenia!

This is the work we are doing together for the community today. We wholeheartedly appreciate the support of those who join us in this collaborative effort as we strive to positively impact the lives of those affected by CTNNB1 syndrome. Together we are committed to this cause and only together we will make significant changes in the lives of our wonderful children.

By Train:

For those arriving by train, Ljubljana is easily accessible from all major European cities. We recommend visiting the DB TravelService for comprehensive information on train routes and schedules.

Travelers choosing to drive to the conference can enter Slovenia through various border crossings with neighboring countries such as Italy, Austria, Hungary, or Croatia. Alternatively, you have the option to rent a car from one of the local car rental agencies. Slovenia’s highways are well-maintained and clearly marked for your convenience. For detailed driving directions and road information, consult resources like ViaMichelin and the national Automobile Association, AMZS.

By Plane:

If you plan to arrive by plane, the primary international gateway is Ljubljana Jože Pučnik Airport, situated just 25 km from Ljubljana. This airport offers convenient access to the region and boasts approximately 240 direct scheduled flights per week from major European hubs. You’ll find a variety of airlines serving this airport, including members of Star Alliance and Skyteam, as well as low-fare carriers like easyJet and Wizz Air. Additionally, there are alternative airports in the vicinity, such as Trieste Airport in Italy (125 km to Ljubljana), Klagenfurt Airport in Austria (120 km to Ljubljana), and Zagreb Airport in Croatia (147 km to Ljubljana).

Airport Transfers to Ljubljana:

We recommend shuttle services by two providers for transfer to or from Ljubljana and nearby airports or cities (Ljubljana Airport, Maribor, Trieste, Venice, Treviso, Zagreb….):

1. GoOpti 

GoOpti offers adaptable low-cost transfers to/from airports and cities, which are instantly confirmed, 100% reliable and carried out by skilled drivers and clean modern vehicles. Further GoOpti transfer information and contacts are accessible following the GoOpti link above.

Nomago offers shuttle transfers to/from Ljubljana and Ljubljana Jože Pučnik Airport. Please follow the Nomago link above to book your transfer. Feel free to contact Nomago for all transportation services and questions (shuttle@nomago.si and prevozi-lj@nomago.si for booking a private transfer).
Important Note:  We advise against using non-pre-booked taxi services offered by the airport taxi association at Jože Pučnik Airport. These services often come with excessively high one-way costs, ranging from 60 to 100€ for a taxi fare from Ljubljana airport to downtown hotels in Ljubljana. Opting for the recommended shuttle services will offer you a more affordable and reliable transportation option.
