A child with the tentative diagnosis of Alagille syndrome is reported. Additional renal abnormalities are unilateral kidney agenesis and a kidney with subcortical cysts with decreased function. At the age of 5 years, insulin-dependent diabetes mellitus developed, with the pancreas being atrophic and negative pancreatic islet cell antibodies.
Conclusion: This observation extends the picture of Alagille syndrome and suggests an overlap with renal-hepatic-pancreatic dysplasia (Ivemark syndrome).
