Diffuse hazy opacity of the right cornea in a patient with<unk> .<unk>  results in familial high-density lipoprotein deficiency. High-density lipoproteins are created when a protein in the bloodstream, Apolipoprotein A1 (apoA1), combines with cholesterol and phospholipids. The cholesterol and phospholipids used to form HDL originate from inside cells but are transported out of the cell into the blood via the ABCA1 transporter. People with<unk>  have defective ABCA1 transporters resulting in a greatly reduced ability to transport cholesterol out of their cells, which leads to an accumulation of cholesterol and phospholipids in many body tissues, which can cause them to increase in size. Reduced blood levels of high-density lipoproteins is sometimes described as hypoalphalipoproteinemia. People affected by this condition also have slightly elevated amounts of fat in the blood (mild hypertriglyceridemia) and disturbances in nerve function (neuropathy). The tonsils are visibly affected by this disorder; they frequently appear orange or yellow and are extremely enlarged. Affected people often develop premature atherosclerosis, which is characterized by fatty deposits and scar-like tissue lining the arteries. Other signs of this condition may include an enlarged spleen (splenomegaly), an enlarged liver (hepatomegaly), clouding of the cornea, and early-onset cardiovascular disease.
