Investigating congenital disorders of glycosylation
Clinical and Basic Investigations Into Known and Suspected Congenital Disorders of Glycosylation and Deglycosylation
This study is looking to learn more about congenital disorders of glycosylation by gathering information and samples from people of all ages who have or might have these conditions.

What this trial studies
This observational study aims to enhance understanding of congenital disorders of glycosylation (CDGs) by characterizing their etiology and natural history. Participants aged 1 month to 80 years with known or suspected CDGs will be evaluated through medical history, physical exams, and possibly telehealth consultations. The study will involve both inpatient and outpatient assessments, with a focus on gathering biological samples for further research. The goal is to expand knowledge about these complex disorders and improve diagnostic approaches.
Who should consider this trial
Good fit: Ideal candidates include individuals aged 1 month to 80 years with known or suspected congenital disorders of glycosylation.
Not a fit: Patients under 1 month of age or those over 2 years who are not medically stable may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to better diagnosis and management of congenital disorders of glycosylation, improving patient outcomes.
How similar studies have performed: Other studies have explored congenital disorders of glycosylation, but this specific approach to characterizing their etiology and natural history is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
* INCLUSION CRITERIA: Participants 1 month or older will have been or will be referred to this protocol with a known or suspected CDG. Participants over two years of age will be admitted only if they are medically stable and require admission to the Clinical Center for diagnosis. One or more probands may be admitted to the NIH Clinical Center for investigation as well as carrier family members. Some participants will be relatives of patients with known CDG s, and their specimens will be obtained for the purpose of heterozygote testing and to serve as controls to help diagnose the proband. Participants may be seen as inpatients, outpatients or via Telehealth. In some cases, biologic samples may be obtained remotely and sent to the Gahl lab. EXCLUSION CRITERIA: * Participants under 1 month of age will not be seen at the NIH Clinical center because care is more readily proffered to older individuals at the Clinical Center. * Participants over two years of age will not be admitted if they are medically unstable and do not require admission to the Clinical Center for diagnosis. * Pregnant women and newborns are excluded.
