VDR and migraine disorder: Motaghi et al. assessed the relationship between two vitamin D receptor (VDR) gene polymorphisms (i.e., TaqI f/F and FokI t/T) and migraine in a cross-sectional study including 103 patients with episodic migraine (85 females and 18 males; mean age 34 ± 1 years) and 100 healthy nonmigraineurs (78 females and 22 males; mean age 35 ± 1 years) [27].
