Of those, right view is the forerunner [ There is this world and the next world.
When these sugar molecules are attached to proteins, they form glycoproteins; when they are attached to lipids, they form glycolipids. Glycoproteins and glycolipids have numerous important functions in all tissues and organs.
Glycosylation involves many different genes, encoding many different proteins such as enzymes. A deficiency or lack of one of these enzymes can lead to a variety of symptoms potentially affecting multiple organ systems.
CDG can affect any part of the body, and there is nearly always an important neurological component. CDG can be associated with a broad variety of symptoms and can vary in severity from mild cases to severe, disabling or life-threatening cases.
CDG are usually apparent from infancy. Individual CDG are caused by a mutation to a specific gene. Most CDG are inherited as autosomal recessive conditions. Introduction CDG were first reported in the medical literature in by Dr.
Jaak Jaeken and colleagues. More than 80 different forms of CDG have been identified in the ensuing years. Several different names have been used to describe these disorders including carbohydrate-deficient glycoprotein syndromes. Recently, Jaeken and colleagues have proposed a classification system that names each subtype by the official abbreviation of its defective gene followed by a dash and CDG.
Their severity and prognosis vary greatly depending upon the specific type of CDG. The specific symptoms and their severity can vary even among individuals with the same subtype and even among members of the same family. In addition, most subtypes of CDG have only been reported in a handful of individuals, which renders it difficult for physicians from developing an accurate picture of associated symptoms and prognosis.
It is important to note that affected individuals will not always have all of the symptoms discussed below. Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis.
Because of the limited number of individuals and the overall lack of knowledge about many of the subtypes of CDG, NORD only provides very brief descriptions of most of these disorders.
Most of the CDG do not have a specific clinical picture. As these disorders become better known and more affected individuals are identified, researchers should be able to obtain a better clinical understanding of the CDG. NORD does have individual reports on several of the better known disorders, which is noted in the individual descriptions below.
In such cases, simply use the specific disorder name as your search term in the Rare Disease Database. Despite the wide variety in presentation, many subtypes of CDG have a significant neurological component involving the central nervous system. Common neurological symptoms include diminished muscle tone hypotoniaseizures, deficits in attaining developmental milestones developmental disabilityvarying degrees of cognitive impairment, and underdevelopment of the cerebellum cerebellar hypoplasiawhich can cause problems with balance and coordination.
Additional common symptoms include abnormal fat distribution, defects in blood clotting that can cause abnormal bleeding or clotting coagulation defectsgastrointestinal symptoms such as vomiting and diarrhea, eye abnormalities such as crossed eyes strabismus and retinal degeneration, and abnormal or distinctive facial features facial dysmorphism.
Feeding difficulties leading to failure to thrive is also common. Failure to thrive is defined as the failure to grow and gain weight as would be expected based upon age and gender. Additional symptoms include liver abnormalities, heart abnormalities such as disease of the heart muscle cardiomyopathystroke-like episodes, and excessive loss of proteins from the gastrointestinal tract protein-losing enteropathywhich can cause swelling due to fluid retention edema.
Fluid accumulation around the lungs or hearts pleural or pericardial effusions has also been reported. The CDG comprising the disorders of protein glycosylation are broken down into two groups known as disorders of N-glycosylation and O-glycosylation. These oligosaccharides are created in a specific order to create specific sugar trees, which are then attached to proteins on various cells.
Disorders of N-glycosylation are due to an enzyme deficiency or other malfunction somewhere along the N-glycosylation pathway. As long as the defect is not identified, disorders of N-glycosylation are subdivided into defects of oligosaccharide assembly and transfer CDG-Ix and defects in oligosaccharide trimming and processing that occur after they are bound to proteins CDG-IIx.
As soon as the defect in an individual patient is clarified, a CDG name is given according to the current nomenclature.
Disorders of N-glycosylation include: More than individuals have been identified. The disorder can be broken down into three stages: This disorder was formerly known as CDG-Ia. The disorder is characterized by profoundly low levels of blood sugar hypoglycemiascarring fibrosis of the liver, failure to thrive, and cyclic vomiting.
Some individuals may develop recurrent blood clots thrombosesgastrointestinal bleeding, and protein-losing enteropathy.
Additional symptoms can include vomiting, diarrhea, abdominal pain, and an enlarged liver hepatomegaly. The specific symptoms vary greatly even among members of the same family. This disorder was formerly known as CDG-Ib.Feb 09, · Rubella virus is transmitted from person to person via the aerosolized particles from the respiratory tract.
A history of exposure may not be present. Individuals may acquire the infection from a completely asymptomatic patient or from an individual shedding the virus during the incubation period.
