Human T-cell leukemia virus type I is a member of the African subtype of simian viruses (STLV).
The nucleotide sequences of the long terminal repeat (LTR) of simian retroviruses (STLV), which are closely related to human T-cell leukemia virus type I (HTLV-I) were found to be of at least two subgroups: an Asian subtype in macaques and an African subtype in African green monkeys and chimpanzee. The nucleotide sequence of HTLV-I was found to be included within the divergence among STLV, but showed closer homology (95%) to African subtype STLV than to Asian subtype STLV (90%).
