However, in stratified analysis, we found that either the rs2910164 C allele or the CC genotype was protective against bladder cancer, prostate cancer, cervical cancer, and colorectal cancer, whereas it was a risk factor for papillary thyroid carcinoma and squamous cell carcinoma of the head and neck (SCCHN).
Then we supposed a possible progression from BN to PTC which may involve rs2910164 in and performed a multivariate logistic regression analysis of PTC/BN and BN cases to determine risk factors of this progression.
In an association study of 608 PTC patients and 901 controls, we found marked differences in genotype distribution of rs2910164 (P = 0.000002), the GC heterozygous state being associated with an increased risk of acquiring PTC (odds ratio = 1.62, P = 0.000007), and both homozygous states protective with odds ratio = 0.42 for the CC genotype (P = 0.003) and odds ratio = 0.69 for the GG genotype (P = 0.0006).
