type I familial hyperlipoproteinemia medical definition

Familial hyperlipoproteinemia marked by the increased serum concentrations of chylomicrons and triglycerides, which decrease if the diet becomes fat free, decreased concentrations of high- and low-density lipoproteins, which increase if the diet is fat free, and decreased tissue lipoprotein lipase activity. It is marked by paroxysms of abdominal pain, enlargement of the spleen and liver, and eruptive xanthomas. Also called familial fat-induced hyperlipemia, familial hyperchylomicronemia, familial hypertriglyceridemia.
