NIH Awards $5.4 Million to Multi-Institutional Consortium to Investigate Neurological Symptoms in CDG We are thrilled to share that a consortium of five research institutions, centered at the Icahn School of Medicine at Mount Sinai, has been awarded a prestigious NIH Program Project Grant (P01) from the National Institute of Neurological Disorders and Stroke (NINDS) titled “Investigation of Neural Pathogenic Mechanisms Associated with Congenital Disorders of Glycosylation.” This five-year, $5.4 million initiative will focus on investigating how the glycosylation defects in different CDGs impacts the cells in the brain and central nervous system— a question of critical importance as nearly all CDG patients have some neurological symptoms but we still don’t fully understand the reasons why these symptoms develop. This gap in our understanding is delaying the identification and testing of new therapies. This new NIH-funded program aims to fill that gap by taking advantage of the experimental strengths of three different model systems – zebrafish, fruit flies and brain organoids or “mini-brains” that can be grown in the lab. The Program consists of three highly integrated Research Projects that will use these different model systems to make discoveries that will then be shared with the other groups. This sharing of information will greatly accelerate the research. This cross-talk and integration is a key aspect of the P01 Program Project grant. The effort is led by two Principal Investigators, Dr. Eva Morava-Kozicz at Icahn School of Medicine at Mount Sinai and Dr. Richard Steet at the Greenwood Genetic Center (GGC), who bring combined strength in clinical and basic science aspects of CDG. The Multi-omics Core of the Program, led by Dr. Akhilesh Pandey at the Mayo Clinic, will bring state-of-the-art technologies like glycomics, glycoproteomics, and metabolomics to the team, supporting each Research Project. The three integrated Research Projects capitalize of the strengths of different model systems and the unique research expertise of the investigators: • Research Project 1, led by Dr. Heather Flanagan-Steet at GGC, will use zebrafish models of PMM2-CDG and PIGA-CDG to examine how glycosylation defects affect different cell types during brain development. • Research Project 2, led by Dr. Clement Chow at the University of Utah School of Medicine, will utilize Drosophila (fruit flies) models to explore different mutations and cell types drive neurological disease in CDG. His work also aims to uncover how genetic background may alter disease progression. • Research Project 3, co-led by Dr. Tamas Kozicz at Mount Sinai and Dr. Steven Sloan at Emory University, will apply human brain organoid models of PMM2-CDG and ALG13-CDG to investigate how altered glycosylation and metabolism disrupt the circuits that transmit signals in the brain. This collaborative and exciting research program brings together a powerhouse team of seven investigators from five leading institutions, combining basic science, clinical expertise, and a broad collection of model systems to accelerate our understanding of why the brain and central nervous system are so affected in CDG. The investigators envision that discoveries made in the initial CDGs that will be studied here will inform our understanding of multiple related CDGs and may open up opportunities to explore common modes of treatment.

We’re thrilled to announce that CDG CARE is now an official member of COMBINEDBrain - The Consortium for Outcome Measures and Biomarkers for Neurodevelopmental Disorders! 💚🧠 This powerful alliance of rare disease professionals, scientists, and advocacy organizations is devoted to speeding the path to clinical treatments for people with rare genetic neurodevelopmental disorders by pooling efforts, studies, and data.

📢Families with rare diseases often rely on Medicaid as their primary or secondary insurance provider. Last week, the House passed legislation that puts Medicaid as we know it and rely on it at risk. Over 8 million families are at risk of losing their Medicaid. But there is still time to prevent the worst cuts and changes in the Senate. ☎️Please call now and tell your U.S. Senator what Medicaid means to you and your family in just a few easy steps: 1. Call 202-224-3121 to ask to be connected to your state’s Senator (there are two for each state, so repeat this step) 2. Tell the staff person who answers the phone what Medicaid does for your family and what would happen if those benefits were taken away. The staff is there for people just like you, and they share the numbers of concerned callers with your senator each day. Don’t be intimidated because you’ve never done this before. Make sure you are counted! Too much is at stake 3. Repeat Step #1 because every state has two Senators 4. If you have a few more seconds, please share this to spread the word to your family and friends! #savemedicaid #rarediseaseawareness #cdgawareness #calltoaction

Hope in Action: The ALG13-CDG Research Project Begins! CDG CARE is proud to announce the kickoff of a groundbreaking new research initiative in partnership with Perlara and the extraordinary ALG13-CDG community, led by the Hale family and their 10-year-old daughter, Siena. Siena is one of fewer than 100 children in the world living with ALG13-CDG, a rare and life-limiting genetic disorder. Her parents, Keszia and Bryce, have turned heartbreak into action – leading a global effort to raise funds and launch a drug repurposing project aimed at improving quality of life and giving children like Siena a brighter future. Thanks to the incredible generosity of families and supporters, over 70% of the funding goal for Phase 1 and 2 has already been raised. This research will use Perlara’s innovative yeast model to screen over 8,000 compounds in search of treatments that could restore function and improve quality of life. If successful, this could be life-changing – not just for ALG13-CDG – but potentially for many CDG types that share similar pathways. With over 190 known CDG types, every step forward for one is a step forward for all. This project is more than research, it’s a movement powered by love, science, and the belief that progress is possible when we work together. Join us. Support the science. Share the story. Be part of the momentum. ocalagazette.com/saving-sien… #SavingSiena #ALG13CDG #CDGCARE #CDGResearch #DrugRepurposing #Perlara #OneCDGCommunity #HopeInAction #StrongerTogether

🚨URGENT ACTION NEEDED The NIH issued a special NOFO a few weeks ago that was framed to open the door for the FCDGC to REAPPLY for our 5-year federal funding support - thanks to YOUR advocacy. BUT… there is now a serious roadblock delaying the release of this opportunity! We CANNOT afford a delay. CDG patients and families are depending on this funding. The FCDGC is our ONLY dedicated research network for CDG. Without immediate follow-through from NIH, this chance could vanish. We are calling on ALL CDG families, friends, and advocates to ACT NOW! Call and email the Rare Disease Caucus leaders TODAY and tell them to demand immediate NIH action: • Rep. Doris Matsui: 202-225-7163 (jackie.weinrich@mail.house.gov) • Rep. Gus Bilirakis: 202-225-5755 (leighann.fairley@mail.house.gov) • Sen. Roger Wicker: 📷 202-224-6253 (kendyl_willox@wicker.senate.gov) • Sen. Amy Klobuchar: 📷 202-224-3244 (Charlotte_Griffith@klobuchar.senate.gov) Contact your local representatives and ask them to stand up for CDG research. This issue can’t wait until next week. Tell them: "NIH must release the revised NOFO as intended by May 31st and allow the FCDGC to move forward. Lives are at stake. Families are waiting. CDG research must continue." SHARE. TAG. FORWARD. Post your calls and messages using #SaveFCDGC and #CDGCommunity. Our strength is in our voices - LET THEM HEAR US.
