Although Cameroon, in west central Africa, has a relatively low HIV prevalence of 5–6%, all HIV-1 groups (M, N, O, and P), nearly all HIV-1 group M subtypes, and numerous intersubtype recombinant forms have been identified in Cameroon. In this report, we describe the near full-length sequence of 04CMU11421, an HIV-1 group M subtype J strain collected in Cameroon in 2004. Phylogenetic analysis of the genome sequence shows high bootstrap support with three subtype J reference sequences in the HIV Sequence database. Therefore, 04CMU11421 represents a fourth pure subtype J isolate and the first reported in Cameroon.
