Defect in ty pe II hyperlipidemia -
Ans. is 'c' i.e., LDL receptor o Familial hypercholesterolemia (type Ila) is due to deficiency of functional LDL receptors as a result of different types of mutations.o Lipoprotein lipase deficiency (Type I hyperlipoproteinemia) results in increased level of ehylomicrones.
