Genetic Polvmorphism of Protease Inhibitor (Pl) in Korean Population

한국인 집단에서 Protease inhibitor(PI)의 유전적 다형

The genetic polymorphism of Protease inhibitor (Pl) in Korean population was investigated by using isoelectric focusing (IEF) in an ultra-narrow pH range,4.2-4.9, and immunoblottins. Three common alleles (Pl * Ml, Pl*2, Pl * M3) were observed and the frequencies for the alleles were Pl * M1=0.7843, Pl * M2=0.1613, Pl * M3=0.0323. In addition to the three common alleles, rare alleles (Pl *5, Pl * Z, Pl* H were detected at low-level frequency. Two unknovlm variants, which were not reported on previous studies in Korean population, were also found.
