A Novel Codon Insert in Protease of Clade B HIV Type 1

AIDS Res Hum Retroviruses. 2009 May;25(5):547-50. doi: 10.1089/aid.2008.0310.


A novel combination of three codon inserts in the pol coding region of HIV-1 RNA was identified in a highly antiretroviral experienced study subject with HIV-1 infection. A one codon insert was observed in the protease region between codon 40 and 41 simultaneously with a two codon insert present in the reverse transcriptase region at codon 69.
