Peroxisome Biogenesis Disorder 9b C2749346

Published: July 22, 2026Updated: August 20, 2026

A severe disorder where faulty genes prevent proper formation of peroxisomes, important for breaking down fatty acids. This causes severe intellectual disability, vision and hearing problems, and liver disease. Treatment involves managing symptoms and preventing complications.
