Write answer in between .Q:A 2-month-old boy is brought to the emergency department 25 minutes after having a seizure. He has had multiple seizures during the past week. His mother has noticed that he has become lethargic and has had a weak cry for the past month. He was born at 37 weeks gestation. He is at the 20th percentile for height and 15th percentile for weight. His temperature is 36.7C 98F, respirations are 50min, and pulse is 140min. Examination shows a soft and nontender abdomen. The liver is palpated 4 cm below the right costal margin; there is no splenomegaly.

A: Glycogen branching enzyme, B: Galactose 1-phosphate uridyltransferase, C: Fructokinase, D: Glucose 6-phosphatase, E: Acid maltasen,  <response>: This is a clinical vignette describing a 2-month-old infant with a history of seizures, lethargy, weak cry, and failure to thrive. The key findings on exam are hepatomegaly and laboratory evidence of hypoglycemia, hypertriglyceridemia, hypercholesterolemia, and lactic acidosis. The differential diagnosis includes metabolic disorders that can cause seizures and hypoglycemia. Based on the lab findings, the most likely diagnosis is a deficiency in glucose-6-phosphatase, which is required for the final step of gluconeogenesis and glycogenolysis. Deficiency of this enzyme leads to hypoglycemia, lactic acidosis, hyperlipidemia, and hepatomegaly. The other enzyme deficiencies listed would not explain the full clinical and laboratory picture.D: Glucose 6-phosphatase
