title: Three examples of anti-Fy3 produced in Negroes.
abstract: We present three examples of anti-Fy3 produced by Negroes. Results of serologic studies were similar to those of previously reported examples of Negro produced anti-Fy3, including negative to weak reactivity with cord red blood cells, separable anti-Fya, and the presence of multiple unexpected alloantibodies. These findings reinforce the difference between anti-Fy3 produced by Negroes and that produced by non-Negroes. The rare formation of Duffy antibodies by Negroes may signify the presence of an amorphic gene at the Duffy locus.
