In the control group, 92 volunteers (82.1%) inherited CC genotype, 18 individuals (16.1%) had CA genotype, and 2 (1.8%) had AA genotype. The frequency of CC, CT, and TT genotypes of 1014C/T SNP in CCR4 gene was 60 (53.1%), 43 (38.1%), and 10 (8.8%) in the patients, and 57 (53.3%), 43 (40.2%), and 7 (6.5%) in the control group, respectively. There were no statistically significant differences between the patients and controls in terms of 16C/A polymorphism in CCL22 (P = 0.816) and 1014C/T SNP in CCR4 1014C/T gene position (P = 0.801). Nevertheless, the study of their association indicated that inheriting the CC genotype of CCR4 was significantly associated with higher stages (stages 3 and 4) in thyroid cancer.Conclusion: 1014C/T genetic variation in CCR4 and 16C/A polymorphism in CCL22 were not found to have a role in genetic susceptibility to thyroid cancer. Inheriting CC genotype at 1014 locus in CCR4 may; however, affect cancer progression in patients with thyroid cancer. %U https://mejc.sums.ac.ir/article_47612_92678e306b8b4f5fc5803a67e5caa8af.pdf
