Abstract: Zidovudine resistance (ZDV-R) is associated with classic genotypic changes at codons 41, 67, 70, 210, 215, and 219 of the human immunodeficiency virus type 1 (HIV-1)
reverse transcriptase (
RT) gene as well as with the multinucleoside resistance (MNR) complexes (
Q151M MNR complex; 6-bp insertion/
A62V complex).
