From: Nucleotide identity and variability among different Pakistani hepatitis C virus isolates
Phylogenetic tree of HCV 5'UTR (nt 35 to 319) sequences of 100 HCV isolates. To identify the origins of the samples, the isolates of HCV patients belonged to areas of Punjab, N.W.F.P., Sindh or Balochistan are designated as PP, PN, PS or PB respectively. Sequences for each major subtype were selected from GenBank database for analysis. The accession numbers of the reference sequences are as follows: M67463 (1a), D90208 (1b), AY051292 (1c), AF238485 (2a), D82034 (2b), D10075 54 (2c), AF046866 (3a), D11443 (3b), D16612 (3c), D16620 (3d), D16618 (3e), D16614 (3f), X91421 (3g), Y11604 (4a), M84845 (4b), M84862 (4c), M84832 (4d), M84828 (4e), 84829 (4f), M8486 (5a), and Y12083 (6a).
