FCDGC

FCDGC’s vision is to provide the best integrated clinical care for congenital disorders of glycosylation (CDG) in the nation so that, from the patient’s perspective, the services delivered are consistent and coordinated.

A strong patient association, committed clinicians and a devoted group of scientists has formed a virtual consortium over the last decade and have closely collaborated to improve patient outcomes. Partners in our consortium have collaborated for many years—sharing knowledge, individualizing therapy, organizing patient conferences, and supporting physicians caring for individuals with CDG patients. We have improved patient care in this rare disease. On this foundation we have set out to establish a nationwide network of regional centers to relieve decades of unresolved questions, address knowledge gaps, develop treatment and meet currently unmet patient needs.

About Clinical Disorders of Glycosylation

Congenital disorders of glycosylation (CDG) is a large group of rare, inherited disorders that affect a complex process in the body call glycosylation. Most children who have CDG have neurological issues and symptoms, developmental problems, growth delays, and problems with organs not working like they should.

Congenital means that CDG is a condition that happens at or before birth. Notice that “disorders” is plural. This is because CDG is not just one disorder, but rather, a group of disorders. There are many types. Which type your child has depends on which body system is affected.

Glycans are sometimes called “sugar trees,” “antennas,” or “sugar chains” by health care providers. They are built from sugar “building blocks.” When some people hear sugar, they think of blood sugar, blood glucose, or diabetes. This is not the case with glycans, which are not used for burning calories. Glycosylation is the process of creating, changing, and attaching these sugar building blocks to proteins and lipids. When the sugar building blocks attach to proteins, they are called “glycoproteins.” When the sugar building blocks attach to lipids, they are called “glycolipids.”

When someone has CDG, his or her body cannot properly add or attach the sugar building blocks to proteins or lipids. Every single system in the body needs the process of glycosylation so the body can function normally. This is why people with CDG have many health problems—because many body systems are affected by glycosylation not working correctly.

Mission

FCDGC’s mission is to improve clinical symptoms as well as improve quality of life and life expectancy of individuals with congenital disorders of glycosylation through advancing and sharing knowledge, developing and validating new diagnostic tools, and exploring therapeutic options to restore appropriate glycosylation.

Goals

Define natural history, validate patient reported outcome and share knowledge on Congenital Disorders of Glycosylation; Develop and validate new biochemical diagnostic techniques and therapeutic biomarkers for clinical trials; Restore appropriate glycosylation in Congenital Disorders of Glycosylation to improve clinical symptoms and quality of life of patients and their families.
