Similar to a previous study43, we did not identify any variants in some genes that have been previously suggested to be associated with BA or BA-related diseases, such as PKD2 (polycystic kidney disease 2, polycystic kidney and hepatic disease 1), CFC1 (polysplenia), JAG1 (Alagille syndrome) and PKD1L1 (biliary atresia splenic malformation syndrome- BASM). Here, JAG1 is linked to breast angiosarcoma.
