Elevated LDL cholesterol with normal triglycerides and tendon xanthomas suggests: 1). Type IIb hyperlipoproteinemia 2). Type I hyperlipoproteinemia 3). Type IIa familial hypercholesterolemia 4). Type III hyperlipoproteinemia
LDL receptor deficiency causes isolated elevation of LDL with tendon xanthomas.
The primary function of ABCA1 protein is:1). LDL uptake2). Cholesterol efflux to HDL3). Chylomicron synthesis4). Triglyceride hydrolysis
ABCA1 transfers cholesterol from peripheral cells to Apo A-I, initiating HDL formation.
