Summary Human red cell esterase D was analysed quantitatively in Japanese samples. Among the three esterase D phenotypes there was a significant difference in catalytic activity, with an approximate ratio of 7:5:3 for EsD 1, EsD 2‐1 and EsD 2. With a few inter‐type individuals, the distribution of their activity values was plotted in a tri‐modal curve. These results suggest that the esterase D system in human red cells is qualitatively and even quantitatively controlled by genes.
