you shared the love

thank you!-2 copy

The community came together in a big way for the annual Love Some1 with Glut1 awareness and fundraising event. It was an incredible two weeks of inspiration and motivation as families put their hope for a brighter future into action by sharing stories, dreaming dreams, and celebrating our loved ones for their perseverance and positivity in the face of so many challenges.

Even though we didn't yet reach our big, bold goal of raising $200,000, we did raise more dollars from more donors in honor of more participants than ever before. The current totals are $163,264 raised from 938 individual donors inspired by 51 fundraisers.

We are incredibly grateful for each and every donation and love the reminder of what can be accomplished when we work together.

We will keep tallying and you can still donate!  We look forward to sharing more details on the final results and how your generosity will be invested to provide resources and drive research progress.


Rare Disease Day

Rare Disease Day is observed on the last day of February each year and is set aside as a special day to raise awareness about the impact of rare diseases on patients’ lives every day and to emphasize the need for research. It is also an important opportunity to honor and show solidarity with the millions of rare disease patients around the world who have one of the thousands of different rare diseases that have been identified. Rare disease journeys are often lonely, and it helps so much to be part of a community - both the global rare disease community and our very special Glut1 Deficiency community.

There were special activities that helped shine a light on our disease and our amazing patients and families who teach and inspire all of us. We are so thankful for them all!



Pleasant View Middle School in Pueblo, Colorado honored Rare Disease Day by inviting Terri Weldon to share information with students and staff, highlighting her daughter Makenzy and Glut1 Deficiency. They had a wear jeans for rare genes day and raised $502 for the Glut1 Deficiency Foundation!

Caroline's mom, Marjorie, hosted a special session of family yoga at her studio in Miami in honor of Rare Disease Day and the Love Some1 with Glut1 campaign. Participants came together to raise awareness and admission was a donation to the Glut1 Deficiency Foundation - check out that yoga gear, too!


 Jyl was a shining star onstage for her "Becoming Miss Amazing" presentation at Manchester University, where she was invited to be a guest speaker. She got to share her story and taught others about Glut1 Deficiency.

Jyl is a current student at Huntington University in their A.B.L.E. Program (Achieving Balance in Life through Education), where she'll graduate in April. She's on the cheer team and has been raising awareness about Glut1 at many sporting events, too! She'll be presenting her story and educating about Glut1 Deficiency at Huntington University in March.



Rick and his mom, Chris, attended a Rare Disease Day event in Grand Rapids, Michigan where there were a number of excellent speakers, including a focus on the sibling journey. Rick and Chris were able to teach others about Glut1 Deficiency, too, and share their story highlighting the long diagnostic odyssey for Rick when he got his diagnosis at age 36.


Sofia and her mother, Sandra, attended Rare Disease Day events in Sugar Land, Texas sponsored by NORD. It was a fun day with exhibits and activities, and they sported their Glut1 Deficiency shirts to raise awareness and visited the 18 booths to share their story and learn from others, too.

Sofia's father, Juan, is a member of the Southwest Cycling Club in the Houston area, and they held a Rare Disease Day gathering again this year to honor Sofia while raising awareness and funds for her Love Some1 with Glut1 fundraising efforts.

Sandra and Executive Director Glenna Steele attended patient-focused Rare Disease Day events from the FDA and NIH. Both were excellent opportunities to hear from leaders at these institutions about their efforts for treatment development and helping rare disease patients through research.

Sometimes, the doctors and researchers who are working so hard to help our loved ones seem like invincible super heroes, and in many ways they are! Their heart, compassion, and dedication for our community remind us that they are indeed very human, and sometimes also the twists and turns of life remind us of that as well.

We are sharing some updates from Dr. Darryl De Vivo and Dr. Juan Pascual below. If you have cards or notes you'd like us to deliver to either of them, please send to us and we'll make sure to forward them on:

Glut1 Deficiency Foundation
PO Box 737
Owingsville, KY  40360

Dr. De Vivo and Dr. Pascual are both such precious and integral parts of our community and to the work of the Glut1 Deficiency Foundation. We are so grateful for them and wish them both the very best!


Dr. De Vivo

Dr. Darryl De Vivo has let us know that he will be transitioning to Professor Emeritus at Columbia University, which means he will be leaving his previous duties there and serving in an esteemed honorary role as he enters retirement.

Dr. De Vivo has served patients and families for decades and has had a storied career in the pediatric neurology field. He was the first author on the 1991 paper describing glucose transporter type 1 deficiency syndrome for the first time in the first two patients ever identified, and our disease is also known as De Vivo Disease.

While we are most fortunate to be able to continue to count on Dr. De Vivo for his wisdom and knowledge on our Medical Advisory Board, we do want to recognize this milestone in his extraordinary career and are planning some special recognition and celebrations - more details to come!

Dear families and friends,

I suffered an accident and have been recovering from surgery. Thank you for all your letters and concern. While I do not seek attention, all the support has truly helped. I feel terrible that two February clinic dates were canceled, disrupting travel plans for several families. These appointments will be or have been rescheduled. March clinics will take place as scheduled, although I will have reduced mobility. I expect to resume full activities, including conferences, by the summer.

Work in the laboratory has continued uninterrupted. Laboratory members were with me since the day of the injury and we continued to meet daily, first via video and now in person. The past few months saw a number of publications from work that started several or, in some cases, many years ago. This represents less than 50% of our recent research. Hopefully, the rest will be published in the coming months as well.

Fortunately, the number of new, potentially important scientific aspects and treatments has been unprecedented. In all candor, sometimes we feel a bit overwhelmed with so many leads to pursue. We do hope, more than ever, that all this work will stimulate others to join the field. As importantly, we could not do any of it without your support, the support of the Glut1 Deficiency Foundation, and the motivation that all of you constantly provide.

Thank you very much.

Warm regards,
Juan M. Pascual

Our t-shirt contest was a huge success - thank you to all who took part! The winning design came from Michelle Mahoney, mom to two daughters with Glut1 Deficiency - Tullah and Myrtle. The special edition shirt sale ended on March 1st, but a new batch was automatically opened in our Bonfire store and we didn't realize that would happen. If you missed the first chance to order, you can get yours now through March 21st!
