The Δ32 allele distribution of the CCR5 gene and its relationship with certain cancers in a Turkish population

The frequency of the Δ32 allele detected in the Turkish population was slightly lower in comparison with the previous reports. The frequency of heterozygote genotypes remained an independent risk factor for the development of breast cancer (odd ratio = 1.628; confidence intervals = 0.442-5.992) as well as other cancers examined in this study.
