(an-al'fă-lip'ō-prō'tēn-ē'mē-ă),

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.
