Write answer in between .Q:A 9-year-old boy is brought to the physician by his mother for evaluation of diffuse bone pain in his right leg. His family immigrated to the United States 6 months ago from northern Canada. He is below the 5th percentile for height and at the 10th percentile for weight. Physical examination shows tenderness to palpation of the right distal femur. There is hepatosplenomegaly. An x-ray of right femur shows generalized trabecular thinning and several osteolytic bone lesions. Laboratory studies show:Hemoglobin 9.2 gdLLeukocyte count 7,600mm3Platelets 71,000mm3A bone marrow aspirate shows mononuclear cells filled with lipid that appear like wrinkled silk. Deficiency of which of the following enzymes is the most likely cause of this patients symptoms?? A: Sphingomyelinase, B: α-Galactosidase A, C: Arylsulfatase A, D: Galactocerebrosidase, E: Glucocerebrosidase,  <response>: Based on the clinical findings of bone pain, hepatosplenomegaly, osteolytic bone lesions, pancytopenia, and lipid-filled cells in the bone marrow, this patient likely has a lysosomal storage disease. The most likely diagnosis is Gaucher disease, which is caused by a deficiency of the enzyme glucocerebrosidase. This leads to accumulation of glucocerebroside in cells of the monocyte-macrophage system. The other enzyme deficiencies listed can cause other lysosomal storage diseases but are less consistent with the clinical scenario described.E: Glucocerebrosidase
