title: A new low incidence red blood cell antigen, Pe.
abstract: A new low incidence red cell antigen (Pe), and its identifying IgG antibody are described. The antigen is destroyed by enzymes and is absent from serum, urine, saliva, and platelets. The Pe gene frequency is estimated to be less than 0.0003, and the Pe locus does not appear to be linked to Rh or Fy, nor carried by the X or Y chromosomes. The clinical significance of this antibody remains to be determined.
