Does biliary atresia affect the second child?

Patient's question:

My childhood friend, but it's been many years since she hasn't had a baby. Because when she was just starting her family and got pregnant, the fetus was diagnosed with biliary atresia. Worried, she didn't dare to have another baby. I wonder if biliary atresia will affect the second child for the doctor who is treating her?

Doctor's answer:

Hello! The typical case of congenital biliary atresia is a full-term delivery, with most being normal, and normal stool color. Jaundice gradually appears 2-3 weeks after birth. In some cases, jaundice occurs in the first few days after birth and is misdiagnosed as physiological jaundice. Various fat-soluble vitamin deficiencies may appear later. Vitamin D deficiency can be accompanied by rickets and widespread epiphyses. Congenital biliary atresia is not a hereditary disease and will not affect the second child.
