초록

목적: 인접 국가에서의 HBV 유전자형 분포를 고려할 때에 국내에서 HBV 유전자형 C가 대부분을 차지하는 현상은 매우 특이하며 전국을 대상으로 하는 연구가 필요하다. 대상과 방법: 내륙과 항구 도시를 포함한 전국에서 수집된 HBsAg 또는 HBeAg 양성 510 검체에 대하여 유전자형 특이 PCR법에 의하여 HBV 유전자형 A-G를 조사하고, 전체 염기서열을 분석한 익산 지역 만성 HBV 보유자에서의 40주와 국내 연구자에 의해 GenBank에 전체 염기서열이 등록된 22주에 대하여 계통 분석을 시행하였다. 결과: PreS-S 분절에 대한 증폭산물이 관찰된 377 검체에서 유전자형 C는 370건 (98.1%)이었으며, 그 외 유전자형은 관찰되지 않았다. 유전자형 B와 C 혼합감염 양상이 7건(1.9%) 있었는데, 이 중 5 검체에 대해 추가로 X분절을 대상으로 하는 유전자형 B 특이 PCR을 시행하였으며, 결과는 모두 음성이었다. 전체 염기서열의 계통 분류를 시행한 국내 HBV 62주의 유전자형은 유전자아형 A2에 속한 1주를 제외하고는 모두 C2로 분류되었다. 결론: 국내에 유행하는 HBV는 거의 대부분 유전자형 C(C2)로 분류되었으며, 그 외 유전자형은 매우 드물었다. 추후 국내에서 기타 유전자형이 발견되었을 때는 확인 과정이 필요할 것이다.

Abstract

Backgrounds/Aims: Considering the incidence of prevailing hepatitis B virus (HBV) genotypes in neighboring nations, the predominance of genotype C in Korea is exceptional and needs to be confirmed by nationwide investigation. Methods: A total of 510 HBsAg (+) or HBeAg (+) serum samples was collected from subjects in several cities and harbors throughout the Korean peninsula for genotype (A-G)-specific multiplex PCR analysis. Another 40 serum samples from chronic HBV carriers from Iksan city were selected for sequencing of the entire HBV genome. Phylogenetic analysis was performed with 22 whole genomic sequences of Korean HBV strains enrolled in GenBank. Results: An amplicon was found in 377 specimens and genotype C occupied 98.1% (370 cases); none of the other genotypes were found. A mixed pattern of genotypes B and C was seen in seven specimens (1.9%), of which five were tested using PCR targeting the X fragment; no genotype B bands were found. With the exception of 1 case, which was subgenotype A2, whole sequences of Korean HBV strains (n=62) belonged to subgenotype C2. Conclusions: The prevailing HBV genotype in Korea is C2; the other genotypes occur only rarely. Future studies should include confirmation of the detection of genotypes other than C.
