The association of VDR gene polymorphisms with serum vitamin D levels and injury predisposition in elite athletes of Kazakhstan

A high prevalence of insufficient 25-(OH)D levels was observed. Vitamin D insufficiency was associated with ethnicity and age. G/G genotype of VDR TaqI polymorphism is associated with vitamin D insufficiency and increased risk of injuries in athletes of an Asian cohort. These findings may be useful for the development of personalized targeted approaches for diagnostics, nutrition, and injury prevention strategies.
