- Abstract
Objectives M184V in HIV-1 reverse transcriptase is among the most common mutations in patients failing antiretroviral therapy but is found only rarely in cases of transmitted drug resistance. Methods To investigate this apparent paradox, we developed an allele-specific real-time PCR (AS-PCR) assay to determine the transmission of M184V in newly infected individuals. Results M184V transmission may occur to a greater extent than previously thought. Persistence of M184V may commonly involve linkage to other drug resistance mutations. The presence of M184V as a single substitution in newly infected individuals was shown to wane over time, as a likely consequence of reversion and overgrowth by more fit wild-type viruses. Conclusions The M184V mutation can be documented in newly infected individuals, and the alternative hypothesis that this substitution might impact on the ability of HIV to be transmitted is unfounded.
