Extracutaneous manifestations: Cholestasis within the first 3 months of life (normal colored or acholic stools). Hepatomegaly is always present. Bilirubin levels are not excessive (70-120 µmol/l), but extremely high cholesterol and lipid levels are found. Typical facies with prominent forehead, sunken eyes and mild hypertelorism as well as a small prominent chin.
