Doctors are asking American Indians to consider donating bone marrow for a transplant to save the life of a 4-year-old Indian girl suffering from a rare form of leukemia.

The appeal to potential Indian donors for Rae Lynn Geshick was made because heredity factors make this the best approach, doctors said Monday.Without the transplant, the girl will probably die within six months, said Dr. Philip McGlave, director of the Adult Bone Marrow Transplant Program at the University of Minnesota.
