Initial Symptoms: Boy with severe headache + violent behaviour
Diagnosis: Hemochromatosis (Cameron)

Contributions by Team
House (2): Notices patient's bones are malformed, realizes illness is hemochromatosis
Chase (1): Identifies liver failure
Cameron (3): Suggests pain in other parts of patient's body is a symptom, diagnosis for hemochromatosis, notices hypogonadism
Foreman (1): Says personality is not a symptom

Notes: Cameron's suggestion of hemochromatosis was rejected by House because it didn't explain the patient's antisocial behaviour, which the team believed was a symptom. House came to the conclusion later by correctly judging that the patient's personality wasn't caused by his illness, for which he was given a credit.
Foreman was correct that the patient had a partial HPRT (hypoxanthine-guanine phosphoribosyltransferase) enzyme deficiency, but this did not affect him so Foreman receives no credit for it.
Foreman received an error for ignoring the patient when he said he had pain in his fingers, which would later prove to be a crucial symptom, and Chase an error for wrongly telling the patient's mother that his illness caused his personality problems. I debated the last one, but in the end decided that it had to be counted. Like Cameron's failures to tell patients that they're dying, it's not part of the diagnostic process but is part of patient care.
