Abstract: Population-based sequence analysis revealed the presence of a variant of human immunodeficiency virus type 1 (HIV-1) containing an insertion of amino acid Ile in the
protease gene at codon 19 (19I) and amino acid substitutions in the
protease at codons 21 (
E21D) and 22 (
A22V) along with multiple mutations associated with drug resistance,
M46I/
P63L/
A71V/
I84V/
I93L, in a patient who had failed
protease
