| LTNP-04-3 | 3/40 (7.5) | |
| LTNP-04-4 | 3/40 (7.5) | |
| LTNP-04-5 | 5/40 (12.5) | |
| Sample PR | PR1 | 18/42 (43) |

| PR3 | 6/42 (14) |
a
vpr genes were amplified by PCR from each PBMC sample (indicated by blue arrows in Fig. 1A), cloned into a shuttle plasmid, and DNA sequences from at least 40 independent clones were determined from each sample.
b
samples 1986, 1996 and 2004 are from the LTNP patient (5071), and sample PR is from the progressor patient (1200).
c
Vpr alleles correspond to the primary amino acid sequences reported in Fig. 1B.
