VDR and cervical carcinoma: Phuthong et al. have detected VDR polymorphism (Fok1, Apa1, and Taq1) in 204 patients with cervical squamous cell carcinoma and 204 healthy controls matched by age, and found that Taq1 was associated with cervical cancer in northeastern Thailand, and Taq1 and Fok1 may interact to affect the development of cervical cancer but no association in APa1103.
