Abetalipoproteinemia (ABL) and familial hypobetalipoproteinemia (FHBL) are rare inborn errors of lipoprotein metabolism. ABL occurs in less than 1 in 1 million persons. FHBL occurs in approximately 1 in 500 heterozygotes and in about 1 in 1 million homozygotes. Approximately one third of ABL and FHBL cases result from consanguineous marriages.
