Familial hypobetalipoproteinemia caused by a mutation in the apolipoprotein B gene that results in a truncated species of apolipoprotein B (B-31): a unique mutation that helps to define the portion of the apolipoprotein B molecule required for the formation of buoyant triglyceride-rich lipoproteins.
A novel nontruncating APOB gene mutation, R463W, causes familial hypobetalipoproteinemia.
