Monozygotic twin girls discordant for acquired immunodeficiency syndrome were born to parents with antibodies to human T-cell lymphotropic virus type III. One twin had clinical evidence of the syndrome with tests positive for antibody, whereas the other at the age of 3 years was clinically, serologically, and virologically normal.
