Donald Fredrickson, then head of the Molecular Disease Branch, became aware of the case and had a hunch that the original diagnosis was incorrect. Clinical and biochemical characteristics of a new case of Tangier disease in Spain. The tonsils are visibly affected by this disorder; they frequently appear orange or yellow and are extremely enlarged.

Study of the first case in Spain. This is a good illustration of how research into rare diseases can sometimes help more common disorders. National Center for Biotechnology InformationU. Lipid metabolism disorders Autosomal recessive disorders Membrane transport protein disorders Skin conditions resulting from errors in metabolism Rare diseases.

Med Clin Barc ; 9: Gastric mucosa appearance in a patient with Tangier disease. Avioli to Tangier Island for further investigation.

Enfermedad de Tangier

Our patient, who was diagnosed with Tangier disease based on lipid metabolism testing, had no orange tonsils. Ann Intern Med ; Therefore, the only current treatment modality for Tangier’s disease is diet modification.


After finding the same symptom in Teddy’s sister and investigation revealing an extremely high number of foam cells cholesterol ester-laden macrophages in not only the tonsils but a wide range of tissues including the bone marrow and spleen, a second trip to the island was made and the discovery was made of very low HDL cholesterol in both the sister and parents of Teddy, evidence for a genetic basis of the disease.

Tangier disease – Genes and Disease. 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. 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.

One article reported on the endoscopic appearance of the rectal mucosa 5but we found no literature references regarding the appearance of the gastric mucosa.

Individuals that are homozygotes for Tangier’s disease develop various cholesterol ester depositions.

The duodenum showed no alterations. It is transmitted in a recessive manner. The cholesterol esters may also be found in lymph nodes, bone marrow, the liver and spleen.

From Wikipedia, the free encyclopedia. se

People with Tangier disease have defective ABCA1 transporters [7] resulting in a greatly reduced ability to transport cholesterol out of their cells, which leads to an accumulation of nefermedad and phospholipids in many body tissues, which can cause them to increase in size.

Homozygous Tangier disease and cardiovascular disease. 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.
