SLC10A1 and chronic hepatitis B virus infection: Our latest study found that the NTCP p.Ser267Phe variant is inversely associated with HBV-related disease progression (Yang et al., 2019), in accordance with several other studies (Wang et al., 2017),we therefore designed this study to investigate whether the NTCP p.Ser267Phe variant exerts an additive anti-HBV effect in chronic hepatitis B (CHB) patients on mainstream NAs treatment.
