Abstract
Background : Alpha-1-antitrypsin (A1AT) deficiency is the only established genetic risk factor for emphysema. This study was undertaken to investigate the prevalence of the genotypes of A1AT genotypes in healthy Koreans. Method : The study population consisted of 380 Healthy Koreans enrolled at the Health Promotion Center in Kyungpook National University Hospital. The polymerase chain reaction (PCR) and restriction fragment length polymorphim (RFLP) for detecting the A1AT variants M1(Ala), M1(Val), M2, S and Z were used. Results : The genotypes of subjects were as follows : M1(Val)/M1(Val), 254(66.8%) ; M1(Val)/M2, 105(27.6%) ; M2/M2, 19 (5.0%) ; and M1(Val)/M1(Ala), 2 (0.5%). There was no case with 'deficiency' alleles such as S and Z found in this study. Conclusion : These results suggest that A1AT deficient alleles are either extremely rare or not present in Koreans.
