Abstract: K103R/Q-containing clinical isolates remained phenotypically susceptible to NNRTI, whereas K103S/T/H-containing isolates showed over 10-fold decreased NNRTI susceptibility.
Abstract: Among patients with a known treatment history, K103S/T/H were observed primarily in individuals failing NNRTI-containing regimens.
Abstract: CONCLUSION: Variants at HIV RT codon 103 other than K103N are observed relatively rarely in clinical isolates, but K103 S, T and H confer decreased susceptibility to NNRTI.
Abstract: Site-directed mutants confirmed decreased susceptibility to
