severe pulmonary and intestinal disease including ileus at birth and liver cirrhosis at the age 5 years, whereas the other one developed much better with only mild pulmonary changes.

At the present time, she shows pulmonary disease and pancreatic insufficiency but not liver disease and develops well under therapy.
