title: Hepatitis C virus genotype 3a with phylogenetically distinct origin is circulating in Pakistan.
abstract: BACKGROUND
  Hepatitis C virus (HCV) is one of the leading causes of viral hepatitis worldwide and its genotype 3a is predominant in vast areas of Pakistan.
  
  
  RESULTS
  The present study reports the first full sequence of HCV 3a isolate PK-1 from Pakistan. This nucleotide sequence was compared with six other HCV genotype 3a full length sequences from different regions of the world by using statistical methods of phylogenetic analysis.
  
  
  CONCLUSIONS
  The nucleotide difference of these seven sequences shows that HCV genotype 3a of phylogenetically distinct origin is circulating in Pakistan.
