Abstract We assessed the viral envelope (V3-V5 region) sequence diversity from 13 HIV-1-infected Indian children from north India. All of the 13 children were found to be infected with subtype C viruses. One of the viral sequences exhibited usage of the CXCR4 coreceptor predicted by Web PSSM and Geno2pheno tools. This virus also had a longer V3 sequence with 37 amino acids, a GRGQ motif, and a methionine residue before it (AIIMS_307). A unique finding was the complete deletion of the V4 region of another virus (AIIMS_363). High sequence diversity was observed in the envelope of the HIV-1-infected Indian children.
