title: A Japanese patient with the rare Rhnull phenotype of the 'regulator type'.
abstract: An example of red cells having no reaction with any Rh antisera was found in a Japanese woman. Results of a serological investigation of the family indicated the action of a 'regulator' gene. Her serum contained an antibody which agglutinated all cells of common Rh types, except for Rhnull, by the saline, anti-globulin and papain techniques.
