Full-length genome characterization of an HIV type 2 isolate from India.
An infectious Indian human immunodeficiency virus-2 (HIV-2) subtype A isolate was completely sequenced and analyzed and its phylogenetic relatedness was investigated. The unusual limited size of the long terminal repeat (LTR) from the isolate was caused due to a truncation within the nef open reading frame (ORF) located at the U3 region of the LTR. The genetic relatedness and lineage of this HIV-2 strain were investigated. The close relatedness of this isolate to West African HIV-2 isolates confirms a geographical entry route of HIV-2 to this part of the Indian subcontinent. This is the first report of an HIV-2 full genome analysis from the Indian subcontinent as well as from Asia.
