[The Alagille syndrome. Apropos 3 cases]. / Síndrome de Alagille. A propósito de tres casos.

The clinical, biochemical, and histopathological characteristics of three patients who had jaundice and other findings suggestive of the syndrome are reported. Studies showed the presence of hypoplasia of the intrahepatic biliary ducts associated with facial, vertebral, cardiovascular, and eye abnormalities and a delay in the weight-height development. This group of abnormalities establish the Alagille syndrome, an entity which has not, until now, been extensively studied in our country.
