Single nucleotide polymorphisms (SNPs) in the VDR gene have been associated with liver diseases, including AIH, PBC, HBV infection, and HCC [32,33,34,35], and with the rapid progression of fibrosis in patients with HCV infection, PBC, and NAFLD [33,36,37]. The gene discussed is VDR; the disease is metabolic dysfunction-associated steatotic liver disease.
