Question Answer
associated with deficiencies of lipoprotein lipaseHyperlipoproteinemia Type 1
Hyper TG, Chylomicrons, Serum milky, High cholesterol, High TG, No AtherosclerosisHyperlipoproteinemia Type 1
Hyperlipoproteinemia Type 1Decreased lipoprotein lipase(LPL) or altered ApoC2-- < 1% (=rare)
idiopathic familial hyperlipemia: eruptive xanthomata of cheek, chin, ear and palateHyperlipoproteinemia Type 1
the most common formHyperlipoproteinemia Type 2
High cholesterol, Clear serum, XanthelasmaHyperlipoproteinemia Type 2
Corneal Arcus,Atherosclerosclerosis positive,Hyperlipoproteinemia Type 2
Associated wtih 4 genetic conditions (autosomal dominant)Hyperlipoproteinemia Type 2
Tendon & Tuberous XanthomasHyperlipoproteinemia Type 2
have only cholesterol LDL receptor deficiency (10%)Hyperlipoproteinemia Type 2 A
have both chol & TG d-ecreased LDL receptor and increased ApoB (40%)Hyperlipoproteinemia Type 2 B
This form is due to high chylomicrons and IDL Hyperlipoproteinemia Type 3
presence of ApoE E2/E2 genotype.Hyperlipoproteinemia Type 3
It is due to cholesterol-rich VLDL (β-VLDL). Prevalence is 0.02% of the population.Hyperlipoproteinemia Type 3
Serum appearance turbid Atherosclerosis +++ (atherogenic)Hyperlipoproteinemia Type 3
TG & cholesterol both greatly elevatedHyperlipoproteinemia Type 3
due to high triglycerides. It is also known as hypertriglyceridemia (or pure hypertriglyceridemia)Hyperlipoproteinemia Type 4
mutation in LP lipase geneHyperlipoproteinemia Type 4
This type is very similar to type I, but with high VLDL in addition to chylomicrons. It is also associated with glucose intolerance and hyperuricemiaHyperlipoproteinemia Type 5
Pancreatitis, Eruptive Xanthomas, Adults,< 5% of totalHyperlipoproteinemia Type 5
defective ABCA1 transporter. Autosomal Recessive Plasma cholesterol very lowFamilial alpha-Lipoprotein Deficiency Tangier's disease
Marked decreased HDL Triglycerides normal Polyneuropathy, lymphadenopathy Orange-yellow tonsilsFamilial alpha-Lipoprotein Deficiency Tangier's disease
Rare congenital Autosomal Recessive Defect in intestineA-beta-lipoproteinemia Bassen-Kornzweig Syndrome
No LDL, VLDL, & Chylomicrons Low Cholesterol & TG Burr cells (acanthocytes)A-beta-lipoproteinemia Bassen-Kornzweig Syndrome
Burr cells (acanthocytes) Failure to thrive Diarrhea, steatorrheaA-beta-lipoproteinemia Bassen-Kornzweig Syndrome
Extremely rare (prevalence 0.01-0.1%) inherited reduced LDL gene mutation of apo B Total cholesterol 70-120 mg/dlHypo-beta-lipoproteinemia
(Low HDL) associated with increased CAD: genetic or secondary to obesity, sedentary, cigarettes, diabetes, nephrotic syndr., medications (beta-blockers, diuretics, steroids, progestationals,..)Hypo-alphalipoprotenemia
