Mary is a fifty-five year old female, who arrived in the ER at 4:35 p.m. with complaints of severe fever and pain.
The attending physician took blood work and revealed that there was a high concentration of oxidative enzymes in the blood such as catalase, D-amino acid oxidase, and uric acid oxidase. In addition, there were relatively high levels of fatty acids in the blood, which the physician suggested they were not being properly metabolized. A density gradient procedure found that an organelle approximately 0.5 microns in diameter was missing. The physician also diagnosed Mary with having gout in the joints in her hands and feet, a condition which is caused by the accumulation of uric acid. That same night around 11:00 p.m., Mary began to lose feeling in her lower back. The doctors performed a routine spinal tap (ST) to see if there was an infection in her cerebral spinal fluid. This test turned out to be negative; however, the attending physician did take a biopsy which revealed the nerve cells in Mary's back were not producing enough myelin, a dielectric material needed for proper nervous system signaling. what disease does Mary have?
