Abetalipoproteinemia (ABL) and familial hypobetalipoproteinemia (FHBL) are relatively uncommon inherited disorders of lipoprotein metabolism that cause low cholesterol levels. [1]  Although persons whose low-density lipoprotein (LDL) cholesterol levels are moderately low (ie, individuals with FHBL) exhibit an enhanced tendency to develop fatty liver disease (FLD), [2]  persons with a profound reduction of LDL cholesterol may have a decreased risk for heart disease.
