CCR2/64I mutation detection in a HIV-1-positive patient with slow CD4 T-cell decline and delay in disease progression

Int J STD AIDS. 2005 May;16(5):392-4. doi: 10.1258/0956462053888817.


Chemokine receptor genetic mutations are among the factors which have been shown to influence human susceptibility to HIV-1 infection and progression. The CCR2-64I mutation has been shown to delay HIV-1 disease progression in some studies. Here we show evidence of delayed disease progression, reflected in maintenance of a stable viral load and a slow CD4 T-cell decline, in a patient with the CCR2-64I gene. We then consider the potential value of identifying these genetic defects in the era of fusion/entry inhibiting therapeutics.
