What are the symptoms and prognosis for individuals with CDG Ix? We are pending tests results from an institute in Belgium to obtain a more specific diagnosis for my 13-month-old son. He has had a liver transplant at 6 months due to liver failure, coagulopathy, ascites, protein losing enteropathy (?), failure to thrive, and hypoglycemia. CT and MRI do not show any brain abnormalities. He does not yet crawl or stand on his own, possibly because he was hospitalized for four months. I am worried about his developmental delay. He does have minimal delay in speech.
