Microangiopathic hemolytic anemia, thrombocytopenia, and acute nephropathy are hallmarks of the hemolytic-uremic syndrome (HUS).1 Though there have been reports of HUS occurring in families,2-6 we are unaware of previous reports of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure occurring simultaneously in parent and child.
