The frequency of CCR5 Δ32 bp (rs333) genotypes in PCOS patients and controls was CCR5Δ32 (59.095%), CCR5(Δ32+Δ32*) (31.81%), and CCR5(Δ32*) (0%) for PCOS patients; and CCR5Δ32 (99%), CCR5(Δ32+Δ32*) (1%), and CCR5(Δ32*) (0%) for controls, respectively (Table 6). The gene discussed is CCR5; the disease is polycystic ovary syndrome.
