Despite multiple exposures to HIV-1, some individuals remain uninfected. This resistance to HIV infection has been associated with homozygosity for a 32-basepair deletion in the CCR5 receptor gene. This variant is frequent in caucasians but extremely rare in Asians and Africans. Identifying variations in the CCR5 gene that affect susceptibility to HIV infection in non-caucasians is therefore of great interest. In this report, we identify 5 CCR5 coding region variants in a Chinese population. The K26R mutation is an undescribed gene variant, whereas 228delK was already found in caucasians and G106R, C178R, and R223Q were previously described in Asian populations and functionally analyzed. As the function of K26R was still unknown, we focused our work on studying its chemokine receptor activity and HIV coreceptor properties compared with wild-type CCR5 and G106R, an already analyzed mutant taken as another control. We observed that K26R displayed alteration in MIP1-beta/CCL4 and RANTES/CCL5 ligand binding and exhibited a slightly decrease for HIV coreceptor properties.
