The major clinical signs of Tangier disease include hyperplastic yellow-orange tonsils, hepatosplenomegaly, and peripheral neuropathy, which may be either relapsing-remitting or chronic progressive in nature. Rarer complications may include corneal opacities that typically do not affect vision, premature atherosclerotic coronary artery disease occurring in the sixth and seventh decades of life (not usually before age 40 years), and mild hematologic manifestations, such as mild thrombocytopenia, reticulocytosis, stomatocytosis, or hemolytic anemia. The clinical expression of Tangier disease is variable, with some affected individuals only showing biochemical perturbations." /><meta name="robots" content="index,nofollow,noarchive" />

The major clinical signs of Tangier disease include hyperplastic yellow-orange tonsils, hepatosplenomegaly, and peripheral neuropathy, which may be either relapsing-remitting or chronic progressive in nature. Rarer complications may include corneal opacities that typically do not affect vision, premature atherosclerotic coronary artery disease occurring in the sixth and seventh decades of life (not usually before age 40 years), and mild hematologic manifestations, such as mild thrombocytopenia, reticulocytosis, stomatocytosis, or hemolytic anemia. The clinical expression of Tangier disease is variable, with some affected individuals only showing biochemical perturbations. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK549920#tangier.Summary" target="NBK549920">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Diagnosis" target="NBK549920">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Clinical_Characteristics" target="NBK549920">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Genetically_Related_Allelic_Diso" target="NBK549920">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Differential_Diagnosis" target="NBK549920">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Management" target="NBK549920">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Genetic_Counseling" target="NBK549920">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Resources" target="NBK549920">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Molecular_Genetics" target="NBK549920">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.References" target="NBK549920">References</a>  |  <a class="medgenPMinfo" href="/books/NBK549920#tangier.Chapter_Notes" target="NBK549920">Chapter Notes</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Tangier disease (TGD) is an autosomal recessive disorder characterized by markedly reduced levels of plasma high density lipoproteins (HDL) resulting in tissue accumulation of cholesterol esters. Clinical features include very large, yellow-orange tonsils, enlarged liver, spleen and lymph nodes, hypocholesterolemia, and abnormal chylomicron remnants (Brooks-Wilson et al., 1999).  <a target="_blank" href="http://www.omim.org/entry/205400">http://www.omim.org/entry/205400</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Tangier disease is an inherited disorder characterized by significantly reduced levels of high-density lipoprotein (HDL) in the blood. HDL transports cholesterol and certain fats called phospholipids from the body's tissues to the liver, where they are removed from the blood. HDL is often referred to as "good cholesterol" because high levels of this substance reduce the chances of developing heart and blood vessel (cardiovascular) disease. Because people with Tangier disease have very low levels of HDL, they have a moderately increased risk of cardiovascular disease.<br /><br />Additional signs and symptoms of Tangier disease include a slightly elevated amount of fat in the blood (mild hypertriglyceridemia); disturbances in nerve function (neuropathy); and enlarged, orange-colored tonsils. Affected individuals often develop atherosclerosis, which is an accumulation of fatty deposits and scar-like tissue in the lining of the arteries. Other features of this condition may include an enlarged spleen (splenomegaly), an enlarged liver (hepatomegaly), clouding of the outermost layer of the eye (corneal clouding), and type 2 diabetes.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/tangier-disease">https://medlineplus.gov/genetics/condition/tangier-disease</a></div></div>
