fa·mil·i·al hy·per·lip·o·pro·te·in·e·mi·a type I

[MIM*238600]
hyperlipoproteinemia characterized by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient consumes a normal diet, and their disappearance on a fat-free diet; low α- and β-lipoproteins on a normal diet, with increase on a fat-free diet; decreased plasma postheparin lipolytic activity; and low tissue lipoprotein lipase activity. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance; caused by mutation in the lipoprotein lipase gene (LPL) on chromosome 8p.
See also: familial lipoprotein lipase inhibitor.

type I fa·mil·i·al hy·per·lip·o·pro·tein·e·mi·a

(tīp fă-mil'ē-ăl hī'pĕr-lip'ō-prō-tēn-ē'mē-ă)
Increased hematologic lipoprotein levels characterized by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient has a normal diet, and their disappearance on a fat-free diet. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance.

type IV fa·mil·i·al hy·per·lip·o·pro·tein·e·mi·a

(tīp fă-mil'ē-ăl hī'pĕr-lip'ō-prō-tēn-ē'mē-ă)
In people following a normal diet plasma levels of very-low-density lipoproteins, pre-β-lipoproteins, and triglycerides are increased, but with normal levels of β-lipoproteins, cholesterol, and phospholipids; may be accompanied by abnormal glucose tolerance and susceptibility to ischemic heart disease.
