A 22 year-old male presents to the emergency department with a swollen and painful right knee. He states that this has happened before, and at home he normally takes factor VIII infusions intravenously three times per week, but he ran out of his medication about one week ago. He states that ice and elevation of the affected joint usually relieve his symptoms but only when he also has his normal factor VIII infusions. His father does not have this disease. On examination he is afebrile, normotensive and crepitus is appreciated in both knees. Which of the following is most likely regarding the disorder?
A. Oxytocin is an effective treatment option for many patients because it results in increased levels of factor VIII released from endothelial cells
B. The patient's sister has a 50% chance of being a carrier for the disease
C. The disease may be caused by parvovirus B19
D. The patient will not pass the mutated allele on to any of his daughter progeny
E. The patient's father is a carrier for the disease
