Living with N syndrome
An extremely rare condition present from birth with facial differences, vision and hearing problems, seizures, and bone differences.
Understanding N syndrome
Features include distinct facial features, vision problems, deafness, seizures, widespread bone differences, stiff muscles, and severe intellectual disability. Boys may have undescended testes or hypospadias. There has been no further description in the medical literature since 1974. GARD lists onset in the newborn period and infancy.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Hearing loss in both ears

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
