Transfusion reactions: Typically mild but may be serious. Although these usually occur immediately they may occur after a delay (up to 24 hours). These reactions are usually caused by Fya or Fyb. Fy3 may cause a reaction but only rarely.
Hemolytic disease of the newborn: This is typically mild but rarely may be serious. Almost always due to Fya: rarely Fyb or Fy3.
