Familial hypercholesterolemia type IIa: defective apo-B100 -?- LDL receptors.

Familial hypertriglyceridemia type IV: due to -?- elevated VLDL's leading to premature atherosclerosis and myocardial infarction.

Combined hyperlipidemia: high plasma cholersterol and/or triglycerides leading to -?- premature atherosclerosis and myocardial infarction.
