Various types of cancer, including melanoma and non-melanoma skin cancer, are associated with vitamin D receptor (VDR) polymorphisms. However, few studies have addressed VDR polymorphisms in patients with mycosis fungoides (MF), and previous studies have reported conflicting results. Aim of this case-control study was to assess the correlation between VDR single nucleotide polymorphisms (SNPs) Cdx2, Fok1, Apa1, Bsm1, and Taq1 and MF. Venous blood samples were collected from 41 patients with MF and 59 age- and sex-matched healthy controls. VDR genotypes of both groups were analyzed. Serum vitamin D levels of patients with MF were also analysed among varying stages and VDR genotypes. Vitamin D levels were significantly low (<30 ng/mL) in 87.9% of the patients (P<0.001). No associations were found between Apa1, Cdx2, Fok1, and Bsm1 SNPs and MF. However, Taq1 polymorphisms were higher in the healthy control group (P<0.001). Our study supports the claim that vitamin D deficiency is common in patients with MF. On the other hand, our findings suggest that Taq1 polymorphisms may be associated with decreased susceptibility to MF. Therefore, VDRs may have complex and heterogeneous effects on the pathogenesis of MF.
