The ITI system in South Koreans and Iranians analysed by an improved classification procedure : distribution of alleles and description of new phenotypes

Phenotype and gene frequency distributions of the inter-α-trypsin inhibitor (ITI) system were analysed in populations from southern Korea and from Iran. The gene frequencies of the common alleles ITI * 1 and ITI * 2 were 0.532 and 0.422, respectively, in southern Korea, and 0.612 and 0.354, respectively,in Iran. The postulated third allele, ITI * 3, was found in the homozygous form
