3.2 Frequency of polymorphisms
We analyzed 273 healthy donors for polymorphisms of the CSF3R gene, and the results showed that there are mainly six SNPs in CSF3R, which can be listed as rs2275471, rs78861150, rs3917981, rs3917980, rs150501885, and rs2275472. Among healthy donors, almost forty-percent had at least one CSF3R SNP, and two SNPs were found concomitantly in 32.96% of these donors, while only approximately 10% of healthy donors carried no SNPs. More details about the heterozygous genotype of the above SNPs and their distribution among healthy donors are listed in Table 2 and Fig 1, respectively.
