The homozygous disorders are identified during infancy or childhood.

  • Persons with homozygous abetalipoproteinemia (ABL) are detected in the first decade of life. Heterozygotes are asymptomatic throughout life.

  • Familial hypobetalipoproteinemia heterozygotes are carriers of the recessive gene that leads to ABL and are asymptomatic. Heterozygotes are usually identified in adulthood after routine blood work, lipid screening, or a workup for gastrointestinal (GI) or neurologic disorders.
