Gene of autosomal recessive hypercholesterolemia

The protein encoded by this gene is involved in LDL receptor binding. Mutations are rare and cause hypercholesterolemia. Autosomal recessive hypercholesterolemia is a bit confusing term because all the mutations causing hypercholesterolemia exert their dose dependent influence.

Gene Regulation

The function of this protein is to direct the synthesized LDL receptor to the sinuoidal membrane of hepatocytes.[Error: Macro 'ref' doesn't exist]
