Understanding Intellectual disability, X-linked, with or without seizures, ARX-related
It can cause delays in learning and development, and some people have seizures. Signs usually begin in infancy or early childhood. Many people have severe intellectual disability that stays about the same over time. Males and females can have it, but females often have milder symptoms or none.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Intellectual disability, often severe
- Flat feet
- Loss of bladder control
- Differences in the testes (dysplastic testis)
- Seizures (less common)
- Low muscle tone (less common)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
