Study Notes
Enzyme Deficiency
- The likely enzyme deficiency in the 4-month-old girl is galactose-1-phosphate uridyl transferase (GALT).
- This deficiency is associated with galactosemia, leading to complications such as cataracts.
Urine Test
- The urine test for glucose oxidase is negative despite the presence of a reducing sugar, indicating galactose rather than glucose in the urine.
Growth and Eating Habits
- Growth curve for the girl suggests growth failure or undernutrition.
- Eating habits may include increased intake of lactose due to the inability to properly metabolize galactose.
Clinical Signs
- Development of cataracts is a significant indicator, often associated with untreated galactosemia.
- Reducing substances in the urine indicate an alternative sugar metabolism issue, often linked with enzyme deficiencies in carbohydrate metabolism.
