A knowledge base
for the global
CDG community

CDG Hub is a knowledge base that is designed to educate researchers, clinicians, patients and families on congenital disorders of glycosylation.

CDG Hub is a nexus for curated information on more than 170+ CDG types, clinical trials, research models and resources, including a database of CDG medical experts and researchers worldwide. CDG Hub aims to unite the global CDG community, increase public awareness, and inspire collaborative research to advance scientific discoveries.

Congenital Disorders of Glycosylation

Congenital Disorders of Glycosylation (CDG) are a large group of rare, inherited disorders that are caused by defects in glycosylation.

Glycosylation is the process of assembling and adding sugar chains, called glycans, to proteins and lipids. When someone has CDG, their body cannot properly create or add glycans to proteins and lipids.

As every part of the body needs glycosylation to work properly, people with CDG have many health problems which often affect multiple body systems. There is no cure for CDG, but treatments are available to manage symptoms and many therapies are currently in development.

170+

There are 170+ different types of CDG and new types are discovered each year.

400+

Over 400 genes in the human genome are involved in glycosylation and mutations in more than 170 of them are known to cause CDG.

Families
