Synonym(s): familial high-density lipoprotein deficiency, Tangier disease [G. an-, priv., + alpha, α, + lipoprotein + -emia, blood] Tangier disease An extremely rare (50 cases reported in world literature) autosomal-recessive condition caused by alpha-lipoprotein deficiency. Clinical findings Generalised deposits of cholesteryl esters in tonsils and other lymphoid tissues, lymphadenopathy, hepatosplenomegaly, proximal peripheral neuropathy, intermittent diarrhoea, corneal opacification. Lab Absent HDL, decreased cholesterol (< 120 mg/dl), decreased phospholipids, decreased apoA-I and apoA-II, increased triglycerides. Prognosis Usually benign, rarely coronary heart disease.an·al·pha·lip·o·pro·tein·e·mi·a (an'al'fă-lip'ō-prō'tēn-ē'mē-ă) Familial high density lipoprotein deficiency; an inheritable disorder of lipid metabolism characterized by an almost complete absence from plasma of high density lipoproteins, and by storage of cholesterol esters in foam cells, tonsillar enlargement, an orange or yellow-gray color of the pharyngeal and rectal mucosa, hepatosplenomegaly, lymph node enlargement, corneal opacity, and peripheral neuropathy; autosomal recessive inheritance.
