title: Sequence determination of hepatitis C virus genome isolated from Taiwan.
abstract: The partial genome sequence of the hepatitis C virus (HCV) was determined in the serum of a Taiwanese patient with chronic community-acquired type C hepatitis. The cDNA fragments synthesized with the HCV RNA as a template were amplified by polymerase chain reaction using specific oligonucleotide primers. The amplified fragments represented the regions coding for the putative core, matrix and envelope proteins as well as the N-terminal amino acid sequence of the nonstructural protein NS1, the partial nonstructural NS3 and NS4 proteins and the region of the partial 5'-end noncoding sequence. The cDNA fragments were cloned and sequenced. Sequence analysis of these clones showed that they share 83.7%, 93.2% and 93.6% similarity at the nucleotide level, and 86.6%, 94.1% and 92.9% homology at the amino acid level, with the previously published American, Japanese and Taiwanese isolates, respectively. Accordingly, the RNA genome we obtained is HCV type II, probably, the predominant subtype in Taiwan.
