Familial extrahepatic biliary atresia.
Only a small number of cases with familial extrahepatic biliary atresia, suggesting a recessive autosomal inheritance, have been reported. However, the cases reported in twins are consistent with an acquired disease. Here the case of two brothers with familial atresia of the extrahepatic biliary system is studied. Diagnosis was confirmed by laparotomy and histologic study of biliary fibrous remnants. In the present cases parental consanguinity might suggest a recessive autosomal inheritance. However, clustering of cases in a family might also suggest a common exposure to responsible factors not so far identified.
