We amplified 228 full-length HIV-1 env genes (range 15-42, median 23 sequences per subject) from paired plasma and DBS samples obtained from 7 subjects with chronic HIV-1 infection who were off antiretroviral therapy (ART) (Fiebig stage VI; n = 6 antiretroviral treatment naïve subjects and n = 1 subject with previous ART experience) (Table 1). The gene discussed is ERVW-1; the disease is HIV-1 infection.
