Abstract:The distribution of serum transferrin subtypes was determined by PAG electrophoresis and isoelectric focussing in a group of 2288 individuals from 10 Mongoloid populations of East Asia. The sample comprised 857 Chinese from different localities: Singapore (239), Malaysia (228), Taiwan (265), Hong Kong (65), Fouzhou (60); Koreans (332), Filipinos (281), Thais (455), Malays (335) and Indonesians (28). The frequencies of Tf C1 varied from 0·73 to 0·79 in the Chinese and from 0·76 to 0·83 in the other Mongoloid populations. Tf C3 was observed at a frequency of 0·02 in the Koreans and Chinese from Fouzhou. Tf DChi was present in a low frequency (0·01 to 0·03) in all the populations. A low frequency of Tf B was also present in all the populations. The phenotypic distribution of transferrin subtypes was at Hardy-Weinberg equilibrium in all the populations.
