[/INST] What are the signs and symptoms of Congenital disorders of glycosylation? The Human Phenotype Ontology provides the following list of signs and symptoms for Congenital disorders of glycosylation. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of adipose tissue 90% Abnormality of coagulation 90% Abnormality of immune system physiology 90% Abnormality of retinal pigmentation 90% Aplasia/Hypoplasia of the cerebellum 90% Aplasia/Hypoplasia of the nipples 90% Cerebral cortical atrophy 90% Cognitive impairment 90% Elevated hepatic transaminases 90% Strabismus 90% Abnormality of the genital system 50% Abnormality of the pericardium 50% Broad forehead 50% Hypertrophic cardiomyopathy 50% Hypoglycemia 50% Seizures 50% Abnormality of the intestine 7.5% Ascites 7.5% Nephropathy 7.5% Peripheral neuropathy 7.5% The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. </s>
