Extractions: TANGIER DISEASE (TD) is a genetic disorder of cholesterol transport named for the secluded island of Tangier, located off the coast of Virginia. TD was first identified in a five-year-old inhabitant of the island who had characteristic orange tonsils, very low levels of high density lipoprotein (HDL) or 'good cholesterol', and an enlarged liver and spleen. TD is caused by mutations in the (ATP-binding cassette) gene on chromosome 9q31. codes for a protein that helps rid cells of excess cholesterol. This cholesterol is then picked up by HDL particles in the blood and carried to the liver, which processes the cholesterol to be reused in cells throughout the body. Individuals with TD are unable to eliminate cholesterol from cells, leading to its buildup in the tonsils and other organs. The discovery of this important cholesterol transport gene may lead to a better understanding of the inverse relationship between HDL levels and coronary artery disease, an important killer in the US. New drugs that regulate HDL levels may be developed and such drugs would not only help individuals with TD, but also people with more common disorders such as familial HDL deficiency. This is a good illustration of how research into rare diseases can sometimes help more common disorders.

Extractions: Tangier Disease is an extremely rare autosomal recessive metabolic disorder. Documentation shows that as of 1988, 27 cases of Tangier Disease had been reported (Makrides pg.465) and in 1992 the reported cases were still fewer than 50 persons worldwide (Thoene pg.265). The majority of the cases tend to localize in one single area of the U.S., Tangier Island, Virginia. The fact that most of the people that are affected by Tangier disease all live in close proximity to one another could be due to Founder's effect. The original settlers to the island came in 1686 and it is possible that one or two of them were carriers of the disease or actually had the symptoms and passed it down through the blood line. Characteristics of Tangier Disease include increased levels or even a complete absence of high-density lipoproteins (HDL) concentrations in one's plasma, low cholesterol levels in the plasma, increased cholesteryl esters in the tonsils, spleen, liver, skin and lymph nodes. One easily visual characteristic usually found in children with Tangier disease is the presence of enlarged, yellow-orange tonsils. Initial research of Tangier disease showed a marked decrease in the HDL concentrations when compared to normal controls. In some cases the reduction was as great as 50% (Schmitz pg.6306). Scientists studied the HDL concentrations and looked for any possible links in its involvement with the disease. They specifically looked at the apo A-I (apolipoprotein) concentrations, which is a major protein component of HDL.

Information on the following diseases can be found in the Related Disorders section of this report: Tangier Disease is an inherited blood disorder involving decreased concentrations of fat compounds in the blood called high density lipoproteins. Large amounts of these compounds may accumulate in certain organs of the body causing tissue discoloration. In later stages, these accumulations may cause organ enlargement and/or blood circulation problems. Tangier Disease is a slowly progressive disorder initially characterized by enlarged orange or yellowish-gray tonsils. This same discoloration may be found in other parts of the throat and/or rectum. In time, the liver, spleen and lymph nodes may become enlarged. Brain dysfunction, loss of tendon reflexes and coronary artery disease may also occur. In some cases, small solid elevated skin lesions (papules) may appear.

Extractions: Disease Sub-Type: Chromosome 9 Pathology In Tangier disease exact link between the underlying cause, and the observed symptoms and physiological effects remain unknown. Tangiers disease is characterised by a defect in the efflux (flowing out of the cell) of cholesterol and its associated esters. This is detected in a large reduction in high-density lipoprotein (HDL) HDL is important because it redistributes fat around the body. On consumption of a meal, fat is first patched into 'chylomicrons' in the intestine. The Chylomicrons are absorbed into the liver, which processes them and releases them as VLDL, and LDL lipoproteins. The VLDL and LDL are distributed throughout the body, and absorbed by a variety of tissues. These tissues and organs then re-emit the particles as HDL lipoportiens to recycle unused cholesterol back to the liver. It is this final step which is in some way defective in Tangiers disease, surprisingly however, it leads to large deposits of cholesterol in the tonsils, and not the more common HDL emmiter tissues, for example muscles. It is thought that the repackaging into HDL requires either a Apolipoprotein mediated mechanism, or a aqueos method. In Tangiers disease it is thought that only the apolipoprotein mediated mechanism is at fault as this method is known to be used by Macrophage cells, which are present in the tonsils.
