CDG Biorepository Program
CDG CARE is proud to partner with COMBINEDBrain to launch the new CDG Biorepository Program – an important global research initiative designed to accelerate scientific discovery and improve readiness for future therapeutic development in Congenital Disorders of Glycosylation (CDG).
Biological samples are among the most valuable resources in rare disease research. Through the CDG Biorepository, individuals and families affected by CDG can voluntarily contribute samples to support biomarker discovery, natural history research, disease modeling, treatment development, and future clinical trial readiness. Sample types may include blood, plasma, dried blood spots, urine, saliva, nasal swabs, and other clinically meaningful specimens depending on study and research needs.
In partnership with COMBINEDBrain, the CDG Biorepository provides the infrastructure, regulatory oversight, storage, and responsible sharing of samples with qualified researchers working to better understand CDG and develop meaningful therapies. Importantly, CDG CARE serves as a governance partner, helping ensure that the use of samples remains aligned with the priorities and best interests of the CDG patient community.
This program represents an important step forward in strengthening the research ecosystem for CDG and ensuring families have a meaningful opportunity to directly contribute to future scientific progress.

*Press Release, April 2022 – CDG CARE awards $50,000 for ultra-rare CDG research!
CDG CARE is honored to announce that donor support has enabled us to fund a $50,000 research grant to the University of Georgia, Complex Carbohydrate Research Center! Through this innovative research project, Dr. Ryan Weiss and his team will establish novel drug screening assays to identify drug candidates for treatment of the CDG, Multiple Hereditary Exostoses (MHE), an inherited skeletal disorder that currently has no approved therapies.
*Press Release, April 2021 – CDG CARE Awards $50,000 Research Grant to Greenwood Genetic Center
CDG CARE has awarded a $50,000 grant to Dr. Heather Flanagan-Steet at the Greenwood Genetic Center to address translational research in CDG. Dr. Flanagan-Steet’s research interests are focused on understanding the molecular and cellular mechanisms driving the development of rare genetic disorders, particularly pediatric disorders like congenital disorders of glycosylation (CDG). The overall goal of her project, “Unraveling CDG complexity using systems approaches”, is to use a PMM2-CDG zebrafish model to identify and test novel therapies. She will evaluate the ability of the recently identified drug, Epalrestat, to reduce PMM2-CDG pathogenesis (development of the disease) and explore the compound’s mechanism of action. The information gained will help identify new therapeutic candidates for patients with PMM2-CDG that may be applicable to other CDGs. The work will be performed at JC Self Research Institute at the Greenwood Genetic Center, whose mission is to provide comprehensive care to patients with genetic disorders.
*Press Release, August 2020 – CDG CARE expands services and research initiatives to support NGLY1 community!
The NGLY1 Foundation | NGLY1.org is excited to announce our union with CDG CARE! CDG CARE is a 501(c)(3) nonprofit public charity that represents all Congenital Disorders of Glycosylation–of which N-glycanase deficiency (NGLY1) is considered a part. NGLY1.org has closely and successfully collaborated with CDG CARE for the past 6 years. There are currently 160+ different types of Congenital Disorders of Glycosylation (CDGs) with very few numbers of patients each. However, collectively the number of patients affected by CDGs is significant and growing. By folding NGLY1.org into the portfolio of CDGs stewarded by CDG CARE, we will be leveraging economies of scale in order to do more in terms of research, awareness and support for the NGLY1 community as well as the greater CDG community. We believe that we are STRONGER TOGETHER. Any future contributions for NGLY1 research and/or support should be made out to CDG CARE with a note in the memo to designate those funds for NGLY1. We are hopeful that this is another big step toward treatments and cures for all!
*Press Release, July 2020 – CDG CARE Funds $50,000 to Support Acetazolamide Clinical Trial in PMM2-CDG
As a result of the promising findings from a Spanish study that suggested acetazolamide may help some individuals with PMM2-CDG with their balance (ataxia), we are starting a clinical trial here in the United States supported by CDG CARE, the Frontiers in Congenital Disorders of Glycosylation Consortium (FCDGC), and the Seattle Children’s Research Institute. We plan to start enrolling individuals, 4 years or older with PMM2-CDG, later this year into this clinical trial. There will be a 6-month period where an individual may get acetazolamide or a placebo, followed by an open label extension where everyone (including those previously on placebo) can receive acetazolamide, if desired. The trial will be performed at Seattle Children’s Hospital (Dr. Irene Chang and Dr. Christina Lam), Mayo Clinic in Minnesota (Dr. Eva Morava-Kozicz), and Children’s Hospital of Philadelphia (Dr. Andrew Edmondson). The trial lasts 2 years, and you will need to travel to one of the study sites every 6 months. Email CDG CARE at research@cdgcare.com for additional information and study location contacts.

*Press Release, Dec 2018 – CDG CARE Awards $40,000 in Research Grants for PIGA-CDG Research
CDG CARE and researchers from Osaka University in Japan enter into a collaboration to lay the groundwork in advancing CDG research for effective supplements in the use of persons diagnosed with a PIGA-CDG mutation. This research will bridge the gap from identification/diagnosis to treatment and if tests prove successful, will mean the first step in identifying a potential treatment for PIGA patients, and other patients on the same enzymatic pathway.
The basis for this project will help determine if these supplements are effective and to what extent they improve the degree of GPI-anchor deficiency. This data will be critical in obtaining future FDA approval for a clinical trial. To learn more about the research and advancements being made in the area of PIGA-CDG, please visit www.piga-cdg.com.
