Hyperlipoproteinemia type 3; Hyperlipoproteinemia type III; Most people with symptoms of hyperlipidemia type 3 have two mutations in the APOE gene, Missing: tipo | Must include: tipo. The lipoprotein disorder now known as type III hyperlipoproteinemia was first described by Gofman et al. in the s and was originally termed “xanthoma Missing: tipo | Must include: tipo. Type III hyperlipoproteinemia (HLP) is usually associated with homozygosity for apolipoprotein (apo) E2 (Arg→ Cys, Arg→ Cys).

Coronary heart disease results from blockage or interruption of the blood supply to the heart potentially resulting in chest hyperlipoproteinemia tipo iii angina and heart attack.
Peripheral vascular disease is a general term for disease of the blood vessels outside of the heart and brain.

It results from blockage or interruption of the blood flow to various organs and the extremities. Decreased blood flow to the legs may result in cramping and cause a limp claudication. Some individuals may have an abnormally enlarged liver or spleen hepatosplenomegaly. Individuals with hyperlipoproteinemia type III may eventually develop inflammation of the pancreas pancreatitis.
Chronic pancreatitis may result in back pain, diarrhea, jaundice, and potentially hyperlipoproteinemia tipo iii development of diabetes. hyperlipoproteinemia tipo iii
Causes Most cases of hyperlipoproteinemia type III are inherited as an autosomal recessive trait. Genetic diseases hyperlipoproteinemia tipo iii determined by two genes, one received from the father and one from the mother.
Recessive genetic hyperlipoproteinemia tipo iii occur when an individual inherits the same abnormal gene for the same trait from each parent. If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms.
Symptoms of hyperlipoproteinemia type III develop due to the improper function or imbalance of special proteins in the blood protein-lipid molecules known as apo E that transport cholesterol and other fats from one area hyperlipoproteinemia tipo iii the body to another and help clear fats from the blood.
Hyperlipoproteinemia tipo iii gene that is responsible for the production of apo E is located on the long arm of chromosome 19 19q The gene occurs in many forms allelesthe three most common of which are known as e2, e3 and e4.
Every person had two apo E genes in some combination of these various forms. Hyperlipoproteinemia tipo iii cases of recessively inherited hyperlipoproteinemia type III result from inheritance of two genes that code for apo e2.

Apo e2 clears dietary fats from the body at a slower rate than apo e3. However, the presence of two hyperlipoproteinemia tipo iii e2-coding genes by itself usually does not result in the development of symptoms of hyperlipoproteinemia type III.
In fact, fewer than 10 percent of individuals with two genes coding for apo e2 ever develop outward symptoms of hyperlipoproteinemia type III.
Researchers believe that additional genetic, environmental, or hormonal factors play a role in the development of the disorder. The primary molecular defect in most patients with type III hyperlipoproteinemia is the presence of a mutant form of apo E apo E-2 that differs from normal apo E apo E-3 by only a single amino acid substitution cysteine for arginine at residue The apo E-2 variant binds poorly to low-density lipoprotein receptors and is associated with a recessive hyperlipoproteinemia tipo iii of inheritance of type III hyperlipoproteinemia.

Other rare forms of mutant apo E causing type III hyperlipoproteinemia appear to be associated with dominant inheritance. The normal catabolism of remnant lipoprotein particles, which is directed by apo E, is altered in type III hyperlipoproteinemia tipo iii.
These particles in turn have a propensity for uptake by macrophages in peripheral hyperlipoproteinemia tipo iii. In addition, an oral overload of 75 g of glucose was administered to determine plasma insulin and glucose levels according to a previously described method.
Results are expressed as hyperlipoproteinemia tipo iii mean the standard deviation [SD]. The differences between variables were determined with nonparametric tests Kolmogorov-Smirnov and Mann-Whitney, and Kruskal-Wallis analysis of variance, including an analysis of trends.
Fisher's exact test was used for the comparison between proportions. Because of the selection criteria, there were no differences between the groups with regard to age, sex, BMI, and waist girth.
Nor were there significant differences in the comparison between hyperlipoproteinemia tipo iii and diastolic pressure between the groups studied.
No significant differences were found in fasting glucose levels among the three groups.

The receptor defect causes levels of chylomicron remnants and IDL to be higher than normal in the blood stream.
