A 4-year-old boy presents with involuntary jerks seen in his upper extremities. The patient’s mother says that “his eyes move in different directions every now and then”. Last winter, the patient had chickenpox but otherwise has always been healthy. His vital signs are a blood pressure of 100/90 mm Hg, temperature of 36.8°C (98.2°F), and respiratory rate of 17/min. On physical examination, the patient’s eyes move chaotically in all directions. Laboratory tests are unremarkable, except for a random urinary vanillylmandelic acid (VMA) level of 18 mg/g creatinine (reference range for children aged 2–4 years: < 13 mg/g creatinine). An abdominal ultrasound shows a 2 cm x 3 cm x 5 cm mass in the left adrenal gland. A biopsy of the mass reveals neuroblasts arranged in a rosette pattern. Which of the following oncogenes is most commonly associated with this condition?
