newborn appears normal at birth, but develops vomiting and diarrhea accompanied by jaundice and
hepatomegaly within the first few weeks of life. Within months, the baby has obvious cataracts and ascites. The
infant is switched to a milk-free diet, which stabilizes but does not completely reverse his condition. By one year of
age, he has developed mental retardation. Which of the following is the most likely diagnosis?
A. Cystic fibrosis
B. Galactosemia
C. McArdle's disease
D. Von Gierke's disease
E. Wilson's disease
