Summer 2020 Newsletter
Back to School
It is back to school time for many families, but this year is different from any other we've experienced. As difficult decisions are being made about in-person or virtual attendance, keeping important accommodations and supports in place, and protecting medically fragile individuals, the Child Neurology Foundation has put together some excellent resources for helping make this difficult time a little easier and better informed.

New Specific ICD-10-CM Diagnosis Code for Glut1 Deficiency
Glucose Transporter Protein Type 1 Deficiency Syndrome, or Glut1 Deficiency, has been assigned its own unique and specific ICD-10-CM diagnosis code in the upcoming addendum to the ICD system, which will take effect on October 1, 2020. Glut1 Deficiency will have the newly created E74.810 code, falling under the E category of diseases representing endocrine, nutritional, and metabolic disorders.
This represents a major milestone for the Glut1 Deficiency community and will be instrumental in future progress for better understanding and better treatments. Previously, a number of different generic codes were used, and there has been no way to accurately track patients and experiences across healthcare systems. The Glut1 Deficiency Foundation is thankful to Dr. Darryl De Vivo and Dr. Juan Pascual for their assistance in helping us submit this new code proposal.

Glut1 Deficiency Syndrome (Glut1DS): State of the Art in 2020
We are anxiously awaiting the official publication of the consensus guidelines paper and the final version is expected any day now in Epilepsia Open. We thank Dr. Jörg Klepper for leading the effort and all those who contributed to this important resource. The G1DF has committed to pay open access fees to ensure that the full text is available free of charge to everyone who wants to read or download it. Dr. Klepper joined our Parent Zoom in July to give us an overview of the paper and answer questions. A transcript has been made available at our website. We will be sure to let everyone know when the final version of the consensus guideline paper is available online. |
Million Dollar Bike Ride - $60,000 Research Grant
Thank you to all who helped us put our hope in motion for the 2020 Million Dollar Bike Ride! The Meisner family put together a wonderful video with submissions from our amazing Glut1 families who walked, ran, rolled, danced, rode, soared, swung, chopped, pushed, pulled, and hoped with us this year.
With your help and support and the generous matching funds from the Penn Medicine Orphan Disease Center, we reached our goal of raising $30,000 for a Glut1 Deficiency scientific research grant and will have our research dollars doubled to $60,000! The request for project proposals will go out soon, and we can't wait to see what comes from this collaboration - thank you again to all who helped, including Team Glut1, Team Taylor (Fields & Friends), Determination for Dominic, and Miles for Millie. |
Research Biobank Repository
The Glut1 Deficiency Foundation and Glut1 Deficiency families are helping facilitate the establishment of a biobank repository at Coriell Institute for Medical Research. The first of the biobank samples have been processed and validated and are ready and available in the catalog! We are fortunate to have iPSC, fibroblasts, and lymphoblastoid cell lines available now for any researcher interested in working with actual Glut1 Deficiency patient samples.
|
Many of you took part in the collection drive at our conference last summer, and we are so grateful for the role you've played in helping make this important resource available. More sample submissions are welcomed and encouraged so more mutations (genotypes) and disease presentations (phenotypes) can be represented. If you are a patient/family and would like to find out more about contributing samples to the biobank, please contact Sherryann Wert or Jose Santana at Coriell.
Connecting Our Community
We have developed a Zoom program to provide opportunities for members of our community to meet up with others no matter where we live! These virtual gatherings give us social time to get to know one another better and offer support and encouragement, and we also have some sessions that are more educational in nature with topics and guest speakers.
We have several different groups meeting on a monthly basis. Make sure you're signed up for our Family Network to get notices, details, and registration links for the meetings. |
Educational Exhibits
Unfortunately, but not surprisingly, all of our planned exhibits have been canceled or postponed from March through the remainder of 2020. We have had the opportunity to participate in a number of webinars, trainings, and consortiums, though, that have been helpful in a variety of areas and allowed us the opportunity continue to raise awareness of Glut1 Deficiency. We look forward to hopefully resuming our in-person professional medical meeting exhibits in 2021.
Family Network and Professional Network
Please visit the link below for more details and to find out why and how you can join us and help us move progress forward as we work for better understanding, better treatments, and better quality of life for Glut1 Deficiency patients and those who love them. These new networks are separate from the mailing list and will require an additional registration. They are open to patients, families, and professionals from all across the globe. Those in the network will have the opportunity to participate in surveys and special activities, share feedback, contribute personal experiences, help identify needs, and help prioritize research and the work of the Glut1 Deficiency Foundation.

Listen to Your Gut and Don't Take "No" for an Answer by Kelly Jones, Communications Director for the Glut1 Deficiency Foundation
Every Glut1 Deficiency patient has a different road to travel, not only to a diagnosis, but with the specific effects they live with as a result of Glut1. This is Chris Holleman’s story. Chris is 22 years old and is the oldest of four brothers. He loves the Indiana Pacers, the Indianapolis Colts, the Dallas Cowboys, and his dogs, Belle and Daisy. Chris lives with his parents, Lloyd and Leslie, and brothers Ryan (19), Luke (15), and Sam (13), in Westfield, Indiana. Chris began having seizures between the ages of one and two years old. As is common with many of our Glut1 patients, many different seizure medications were tried. The medications either didn’t help or came along with undesirable side-effects.
|

“One night, Lloyd sat down at our clunky, boxy computer with the dot-matrix printer and found the World Wide Web,” said Leslie. “He found The Charlie Foundation website and learned about the ketogenic diet. We watched the movie ‘First Do No Harm’ and decided that we needed to talk to his doctors about trying the ketogenic diet.” Chris’ doctors were resistant to trying the diet and didn’t think that it would help. Lloyd and Leslie were not about to take no for an answer and pushed harder. They compiled all of Chris’ medical records and sent them to the Epilepsy Center of the Department of Neurology and Neurosurgery at Johns Hopkins to see if Chris would be a good candidate for the ketogenic diet. Chris began the diet at age two and it made an incredible difference for him.
After two years, Chris’ doctors wanted to start weaning him from the diet. Typically, in general epilepsy, if seizures have been well controlled for two years, the patient is gradually taken off of the diet. “Every time we would try to take him off of the diet, his seizures returned. I just knew there was something else wrong,” said Leslie. The Holleman’s knew that they needed to keep searching for the answer. Little did they know that an accidental phone call would change Chris’ life.
“Did I ever tell you that I accidentally called Jim Abrahams from the Charlie Foundation at 5 a.m. in the morning?” laughed Leslie. Knowing exactly what she was going through as a parent, Jim was gracious on the phone and introduced Leslie to Beth Zupec-Kania. Beth is a Registered Dietitian Nutritionist who has managed ketogenic diet therapies since 1991 and is a consultant to The Charlie Foundation and a member of the Medical Advisory Board for the Glut1 Deficiency Foundation. Beth is also the designer of the online program for creating ketogenic diets, the KetoDietCalculator. One day, Leslie received a phone call from Beth who was attending a medical conference. During a lecture, Beth learned about Glut1 Deficiency Syndrome and told Leslie she really thought that could be what was going on with Chris. After being tested, Chris was diagnosed with Glut1 Deficiency one month before his 10th birthday.

Being on the diet has changed Chris’ life
Chris graduated from high school in 2017. With the help of a job coach through his school, Chris was able to land his first job at Chick-fil-A. “It wasn’t challenging, “ said Chris. One of the skills that many Glut1 patients need help building is self-advocacy. “He was so excited to be working at his first job and we thought that he loved it,” said Leslie. “We were so proud of Chris for advocating for himself by telling us that he needed something more challenging than wiping food trays.” In October of 2019, Chris started an internship at Shepherd Insurance in Carmel, Indiana. He spent two days a week sorting and delivering mail. “I liked to deliver the mail and say hello to people,” said Chris. Due to COVID-19, the office has been closed since March. Leslie shared, “Chris is such a people person that it was a really good fit for him. If you find the right group to support your child, it’s absolutely great.”
In December of 2019, Chris was accepted into Same as U, a full day program for adults with intellectual and developmental disabilities that promotes life-long learning in a college-like atmosphere. During the closure due to COVID-19, Chris was able to continue attending Same as U via Zoom conferencing. He recently was able to start attending again with new safety protocols put into place. “My favorite part about Same as U is being with my friends,” said Chris.
Sharing Learned Experiences with the Glut1 Deficiency Community
We all know how rare Glut1 Deficiency is and have come to rely on each other for information. Leslie Holleman is in the unique position of not only having a son diagnosed with Glut1 Deficiency, but she has always worked in developmental services. “I was working with people who are disabled or have special needs even before Chris was born,” said Leslie, a Qualified Intellectual Disabilities Professional. In 2017, Leslie was invited to be a presenter at the Glut1 Deficiency Foundation Family Conference held in Nashville, Tennessee. Her presentation, “Creating Positive Outcomes in the Glut1 Life” was extremely informational and presented to a packed room of parents. She was again invited to be a presenter at the 2019 conference in Washington DC, where she shared tips on keto independence and self-care.
“Leslie’s unique perspective, both professionally and as the parent of a Glut1 patient, brings a wealth of information to both our community of families and medical professionals,” said Glenna Steele, Executive Director of the Glut1 Deficiency Foundation. “The Holleman family has always provided a positive impact to our community, not only through Leslie’s willingness to share her experiences and knowledge, but also through Lloyd’s work as a founding Board Member for the Glut1 Deficiency Foundation.”

“It feels like we’re home.”
When Chris was diagnosed with Glut1 Deficiency, Lloyd began researching it online. He found that the first ever family conference had happened in Chicago just two months prior. “We made sure to make it to the next one,” said Lloyd. “And we haven’t missed one since!” added Leslie. She continued, “When we go to a conference, we’re around people who get us. It feels like we’re home.” When asked what his favorite part about going to a conference is, Chris shared, “I like hanging out with my friends Claire, Drew, Dalton, Meredith, Macie, and Ben.”
Advice From a Glut1 Family 13 Years After Diagnosis
Lloyd says that they always do their best for inclusion, especially at home. “We try to serve Chris food that is as close to what we’re eating as possible. He might have a turnip when we’re eating potatoes.” One of the most important things, according to Lloyd, is finding a good dietitian and sticking with them.
Leslie shared that one of the most beneficial things to help Chris was working with a Behaviorist to help him to accept his Glut1 diagnosis. Also, focusing on what they can do is important for someone living with a disability or special needs.m“We never let what Chris can’t do get in the way.” She also suggested taking what your Glut1 patient likes and expanding on that. Leslie added, “If I had to do it all over again, I would have involved Chris more in the cooking of his own food to help with independence as he got older.”
Chris’ advice for new Glut1 patients and families: “You should follow the diet.”
