Alpha-Methylacetoacetic Aciduria is a very rare disease. The age of onset is between 6-months and 24-months. Symptoms include severe metabolic acidosis and ketosis. Affected children experience episodes of vomiting, dehydration, difficulty breathing, extreme tiredness, and occasional seizures. These episodes may lead to coma. Death or neurologic complications can also occur.
