Sequence variability of the 5' UTR in isolates of hepatitis C virus in China.

BACKGROUND Hepatitis C virus infection is a great issue in China; however, there is very little information on genotyping investigations based on sequence variability in the 5'untranslated (5'UTR) reported. The present study was to define the sequence variability based on the sequence divergences of the 5'UTR of the virus. METHODS Sequences of 91 isolates… (More)
