Clinical features of sodium taurocholate cotransporting polypeptide deficiency and an analysis of SLC10A1 gene mutation / 临床肝胆病杂志

ABSTRACT

Objective To investigate the clinical and gene mutation features of sodium taurocholate cotransporting polypeptide (NTCP) deficiency. Methods A total of 10 children, aged 50%). Second-generation gene sequencing showed that all 10 children had a homozygous mutation of the SLC10A1 gene, i.e., c.800C > T(p.Ser267Phe, chr14∶70245193). Conclusion Although NTCP deficiency often has no symptoms, some of the children may manifest as infant cholestasis in the early stage. The possibility of NTCP deficiency should be considered when there is persistent hypercholanemia and the changing trend of serum TBA is not consistent with that of other liver function parameters.
