. The rare Kell blood group phenotype K° was detected in a Japanese male when his red cells failed to agglutinate in either anti‐K or anti‐k. Further testing showed that his cells, and those of a brother, did not react with anti‐Kp a , Kp b , Ku, Js s or Js b , but did react with Claasen serum from a rare Dutch phenotype in the Kell system. The sera of the propositus and his brother had no antibodies to any of the Kell antigens. The observed frequency of the K° phenotype in over 14,000 Japanese is 0.000069, similar to that in Caucasoid populations.
