VDR encodes the vitamin D receptor, a member of the nuclear receptor family of transcription factors, which binds to the active form of vitamin D. VDR expression was decreased in melanoma (Brożyna et al., 2014), and VDR variants were associated with a higher risk of PD (Butler et al., 2011; Meamar et al., 2017). The gene discussed is VDR; the disease is melanoma.
