A case of apolipoprotein A-I deficiency due to carboxyl-terminal truncation

Apolipoprotein A-I deficiency is a rare metabolic disease characterized by an impaired reverse cholesterol transport system resulting in excessive cholesterol accumulation. Here, we discuss a case of apolipoprotein A-I deficiency caused by a carboxyl-terminal truncation mutation p.His186ProfsX46 in APOA1, which might result in increased catabolism of the mutant protein.
