A new genetic cause of Congenital Disorders of Glycosylation (CDG) has been identified, according to a recent study in The American Journal of Human Genetics. This means a blood sample can now confirm diagnosis of this form of CDG, notes Andrew C. Edmondson, MD, PhD, an attending physician in Human Genetics and Metabolism at Children’s Hospital of Philadelphia and co-author on the study. Edmondson is one of the founding members of Frontiers in Congenital Disorders of Glycosylation (FCDGC).
A natural history study by the Frontiers in Congenital Disorders of Glycosylation Consortium (FCDGC) is uncovering new insights on liver function in patients with congenital disorders of glycosylation (CDG). A paper published recently in the Orphanet Journal of Rare Diseases based on findings from the study recommends that all CDG patients have at least yearly comprehensive screening for liver disease, including physical exam, lab work, and imaging with ultrasound and elastography.
Seven patients now have a name for their specific congenital disorder of glycosylation (CDG)—a new type called GALNT2-CDG. Researchers from Frontiers in Congenital Disorders of Glycosylation (FCDGC) describe the new disorder, caused by mutations in the GALNT2 gene, in the journal Brain.
