- Proteins, fats, and other molecules are the body s building blocks. Many of these molecules must have sugars, or chains of sugars, attached to work properly. People with congenital disorders of glycosylation (CDGs) cannot attach these sugars or sugar chains properly. A child or adult with a CDG can have symptoms in different parts of the body, including brain, nerves, muscles, liver, and immune system. Researchers want to learn more about these diseases to understand better what is causing the problems.
Objective:
- To learn more about CDGs.
Eligibility:
- People age 1 80 with CDG or suspected to have a CDG.
Design:
-CDG participants will stay in the hospital 3 5 days. They will have:
-Medical history and physical exam. They will answer questions about their CDG.
-Blood taken several times. Their skin will be numbed, then a needle will take blood from an arm vein.
-Samples taken of their skin, urine, and maybe stool and spinal fluid.
-Photos taken of their whole body. They can wear underwear and cover their eyes.
-Brain MRI. They will lie on a table that slides in and out of a metal cylinder. The scanner makes loud knocking noises so they can wear earplugs.
-Abdomen ultrasound. Sound waves take images of the body from the outside.
-Hand/wrist X-rays for young patients. They may have a full-body X-ray.
-DEXA bone density scan. Participants will lie on a table under a scanner.
-Echocardiogram and electrocardiogram for heart activity. Pads are stuck on the skin and the electrical activity of the heart is recorded.
-Tests of hearing, thinking, motor skills, and speech.
- Children participants may have tests done under sedation if it will benefit them directly.
- CDG participants may have other procedures during their visit. They may have follow-up visits every year.
Eligibility
INCLUSION/EXCLUSION CRITERIA:
Patients of any gender and ethnicity age 1-80 years with a suspected CDG based on biochemical tests or a confirmed CDG based on enzymatic or molecular tests will be eligible to enroll in this protocol. Patients will also be excluded if they cannot travel to the NIH due to their medical condition. Infants under age one year or under 10 kg of body weight are excluded because care is more readily provided to older infants at the Clinical Center.
