Population Studies of Serum Protein Variations in Japanese

Abstract

The distributions of group-specific component, haptoglobin and transf errin phenntypes were researched in the blood donors living in Chiba Prefecture (in the suburbs of Tokyo). Blood materials were classfied into several populations according to habitants of individual donors, and the regional differences of each frequency were examined.
The results are shown in Table 1, 2 and 3a. No regional differences were observed in the frequencies of group specific component and haptoglobin types and no rare types of those serum proteins were detected. The obtained results were compared with the frequencies on Japanese reported by other investigators, which were presented in Table 3b, 4 and 5.
