Abetalipoproteinemia (ABL) and familial hypobetalipoproteinemia (FHBL) are caused by genetic defects that encode for MTP or apoB molecules, respectively.

  • ABL is caused by mutations in the MTP gene.

  • FHBL is caused by a mutation in the APOB gene.

  • Secondary hypobetalipoproteinemia may be associated with cancers, liver disease, severe malnutrition, and other wasting disorders.
