Ldlrtm1(LDLR)Mae mutation (2 available); any Ldlr mutation (76 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
homeostasis/metabolism
• decrease in plasma lipid levels that is accompanied by reduction in plasma apoproteins B, E, and AI
• females exhibit a 4-fold reduction in steady state plasma cholesterol when fed normal chow
• when fed a high fat diet, plasma cholesterol levels increase due mainly to the increase in HDL cholesterol, although levels are still lower than in wild-type on a high fat diet

homeostasis/metabolism
• exhibit increased clearance of non-HDL lipoproteins (VLDL and LDL) from plasma
• do not develop type III hyperlipoproteinemia, exhibiting normal plasma cholesterol and triglyceride levels on a normal chow diet
• more resistant to diet-induced hyperlipidemia than single Apoetm1(APOE)Mae homozygotes
