A systematic review analyzing studies on vitamin D-related genetic variations and NAFLD showed that VDR gene polymorphisms rs2228570, rs11168287, rs10783219, and rs4752 were associated with the presence of NAFLD, while NAFLD severity was associated with VDR variants rs2228570 and rs4334089 [25]. The gene discussed is VDR; the disease is metabolic dysfunction-associated steatotic liver disease.
