His mother is concerned about her sons irritability and vomiting, particularly after breastfeeding him. The infant was born at 39 weeks via spontaneous vaginal delivery. His initial physical was benign. Today the newborn appears mildly jaundiced with palpable hepatomegaly, and his eyes appear cloudy, consistent with the development of cataracts. The newborn is also in the lower weight-age percentile. The physician considers a hereditary enzyme deficiency and orders blood work and a urinalysis to confirm his diagnosis. He recommends that milk and foods high in galactose andor lactose be eliminated from the diet. Which of the following is the most likely deficient enzyme in this metabolic disorder?? A: Galactokinase, B: Galactose-1-phosphate uridyl transferase, C: Aldose reductase, D: UDP-galactose-4-epimerase, E: Glucose-6-phosphate dehydrogenase,  <response>: This is a question about diagnosing a metabolic disorder in a newborn based on symptoms of irritability, vomiting, jaundice, hepatomegaly, cataracts, and poor weight gain. The physician suspects a hereditary enzyme deficiency related to galactose metabolism and recommends dietary restriction of galactose and lactose. The symptoms and physicians suspicion point towards classic galactosemia, which is caused by deficiency of galactose-1-phosphate uridyl transferase. This enzyme is needed to metabolize galactose. Deficiency leads to buildup of galactose-1-phosphate which is toxic. Of the choices given, galactose-1-phosphate uridyl transferase deficiency is most consistent with the clinical presentation described.B: Galactose-1-phosphate uridyl transferase
