What are the types of Hyperlipoproteinemia?
There are five types of primary hyperlipoproteinemia:
- Type 1 is an inherited condition.
- Type 2 runs in families.
- Type 3 is a recessively inherited disorder in which intermediate-density lipoproteins (IDL) accumulate in your blood.
- Type 4 is a dominantly inherited disorder.
- Type 5 runs in families.
What is Fredrickson classification of hyperlipidemia?
Fredrickson classification of hyperlipidemias
| Hyperlipo- proteinemia | Synonyms | |
|---|---|---|
| Type II | a | Familial hypercholesterolemia |
| b | Familial combined hyperlipidemia | |
| Type III | Familial dysbetalipoproteinemia | |
| Type IV | Familial hypertriglyceridemia |
What is Hyperlipoproteinemia type 2a?
Hyperlipoproteinemia type IIa is an autosomal dominant disorder caused by mutations in the LDL receptor. The LDL receptor gene consists of a number of distinct functional domains such as signal sequence, ligand binding, and so on.
What is Type 2b Hyperlipoproteinemia?
Definition: Type IIb hyperlipoproteinemia is caused by mutation in the receptor-binding domain of APOLIPOPROTEIN B-100 which is a major component of LOW-DENSITY LIPOPROTEINS and VERY-LOW-DENSITY LIPOPROTEINS resulting in reduced clearance of these lipoproteins.
What is type II hyperlipidemia?
Type II (a and b): Type IIa, or familial hypercholesterolemia, and type IIb, or familial combined hyperlipidemia, both result in high levels of LDL . They can lead to deposits of fat in the skin and around the eyes and can also increase the risk of heart problems.
What is Hyperlipoproteinemia III?
Hyperlipoproteinemia type III is a genetic disorder that causes the body to breakdown (metabolize) fats (lipids) incorrectly. This results in the buildup of lipids in the body (hyperlipidemia) and can lead to the development of multiple small, yellow skin growths (xanthomas).
What is acquired Hyperlipoproteinemia?
Hyperlipoproteinemia refers to a group of acquired and inherited disorders whose common denominator is excessive levels of lipids (fats) in the blood, caused by a metabolic disorder. It is also referred to as hyperlipidemia.
What does hyperlipoproteinemia Frederickson type 1 mean?
Hyperlipoproteinemia Frederickson Type I. Hyperlipoproteinemia type 1 is a rare genetic disorder characterized by dysfunction of lipoprotein lipase or determined apolipoproteins.
What are the symptoms of hyperlipoproteinemia type 1?
Hyperlipoproteinemia type 1 is a rare genetic disorder characterized by dysfunction of lipoprotein lipase or determined apolipoproteins. Patients suffering from this disease present with recurrent abdominal pain due to pancreatitis, hepatosplenomegaly as well as eruptive cutaneous xanthomas.
How are lipid disorders classified according to Fredrickson classification?
Lipid disorders are also classified according to the Fredrickson classification, which is an older classification. In this classification there are five types of hyperlipidemia: Type I: In these individuals elevated chylomicrons are found due to lipoprotein lipase or Apo CII deficiency, causing elevated levels of triglycerides.
What’s the difference between Type I and Type V hyperlipidemia?
Hyperlipoproteinemia type V, also known as mixed hyperlipoproteinemia familial or mixed hyperlipidemia, is very similar to type I, but with high VLDL in addition to chylomicrons. It is also associated with glucose intolerance and hyperuricemia.
