- AB Human T-cell-leukemia virus type I (HTLV-I) is the causative agent of
- adult T-cell leukemia/lymphoma (ATL) and tropical spastic
- paraparesis/HTLV-I-associated myelopathy (TSP/HAM). The different
- disease outcome may be attributable to subtle mutations leading to
- modification of viral tropism or infectivity. Initial attempts found a
- very high level of sequence conservation among all HTLV-I strains.
- However, only one complete proviral DNA sequence is reported from a
- TSP/HAM patient, with a provirus derived from immortalized lymphocytes,
- which might be expected to be a leukemogenic variant rather than a
- neurotropic one. We cloned and sequenced a complete HTLV-I provirus
- (HTLV-IBoi) derived from the uncultured lymphocytes of a sub-acute
- post-transfusional TSP/HAM patient with clonal integration of HTLV-I.
- HTLV-IBoi proviral genome is 9033 bp long, and its overall genetic
- organization is similar to that of the prototype HTLV-I(ATK), without
- major deletions or insertions. No premature termination codon was found
- in the 4 open reading frames of the pX region. Divergence at the
- nucleotide level of HTLV-IBoi from the reported full-length HTLV-I
- varies from 1 to 9.4%, and indicates that it corresponds to a
- cosmopolitan genotype. This study did not identify specific sequences
- associated with neurotropic strains.
