Genetic polymorphisms due to variation in the number of tandem repeats of DNA sequences(VNTRs) provides a useful means for discrimination between individuals. Allele and genotype frequencies of the highly polymorphic Human Thyroid Peroxidase(TPO) gene were determined in Korean population samples by using PCR followed by polyacrylamide gel electrophoresis, a procedure called the amplified fragment length polymorphism(Amp-FLP) technique. In 123 unrelated Korean individuals 10 different alleles and 29 genotypes were observed. The TPO gene demonstrated a heterozygosity of 0.707 and the power of exclusion(POE) was 0.945. The probability of having the same DNA band within two unrelated individuals was 14.6$\times10^{-2}$. The distribution of observed genotypes conformed to Hardy-Weinberg equilibrium($x^2$=4.48, 0.05
