To evaluate the possible prognostic value of Foxa3 on biliary atresia, we detected Foxa3 mRNA expression on all 60 biliary atresia liver samples by qRT-PCR, and divided the patients into Foxa3-high expression group and Foxa3-low expression group by using the median value of Foxa3 mRNA level as a cut-off. Here, FOXA3 is linked to biliary atresia.
