Congenital disorder of glycosylation, type ia

Overview

What is congenital disorder of glycosylation type 1A?

Congenital disorder of glycosylation type 1A (CDG-Ia) is a genetic disorder. In CDG-Ia, the body has a problem with adding sugar molecules to proteins (this process is called "glycosylation"). Glycosylation is an important process to tell proteins where to go, how to be modified, and how to work. Because proteins all over the body need to be glycosylated to work properly, people who have CDG-Ia can have many different medical concerns that can affect many different body systems.

The best person to figure out whether an individual has CDG-Ia is a doctor who specializes in metabolic disorders, such as a biochemical geneticist. A biochemical geneticist can be found by asking your doctor for a referral or looking on the American College of Medical Geneticists website .
