Still trying to make a diagnose

My son is now 12, for the past 2 1/2 years we have been in and out of doctors trying to figure out our growing list of issues. It started with patches of gray hair and mood swings, then precocious puberty, a hamartoma (or neoplasm) of the right cerebral peduncle, then depression and anxiety, and a diagnosis of a mild learning disorder and now asthma and allergies to gluten, casein, and yeast. Also he shows, some autistic traits and some ADHD traits. He is doing better, but he is always fatigued. Tuberous Sclerosis has been mentioned, but no answers. We are currently going to a naturopath and taking supplements for depression, etc. We have been repeatedly told his thyroid is normal. Is there anyone out there that can make some connections or suggestions? This seems like a long list and no one seems to have any answers.
