What causes the symptoms of ALD?
ALD is caused by a variation (mutation) in the ABCD1 gene. Genes provide instructions for creating proteins that play a critical role in many functions of the body. When a mutation of a gene occurs, the protein product may be faulty, inefficient, absent, or overproduced.
How is ALD passed on?
The damaged gene that causes ALD resides on the X chromosome. Boys inherit only one X chromosome, which is passed to them from their mothers. Because girls inherit two X chromosomes, one from each parent, the functional copy inherited from their father usually protects female children from the disease.
What are the signs and symptoms of ALD?
ALD symptoms include:
- loss of vision.
- learning disabilities.
- dysphagia (difficulty swallowing)
- seizures.
- deafness.
- lack of coordination and balance.

- intermittent vomiting.
Is ALD an autoimmune disease?
Our study demonstrates that adult ALD is not immediately associated with the presence of adrenal autoantibodies and suggests that adrenal insufficiency is not mediated by an autoimmune process in adult ALD patients.
When do boys with cerebral ALD show symptoms?

The most common symptoms include: As the condition progresses, other signs and symptoms of cerebral ALD may include: Without treatment, ALD progresses rapidly, often leading to a vegetative state or death within a few years.
Can a doctor Miss early signs of ALD?
Many early symptoms can be missed or blamed on more common and milder health issues like attention deficit disorder (ADD) or learning disabilities. If your doctor suspects ALD, they may order two tests. One is a blood test that looks for a special type of fatty acids that people with ALD have in high amounts.
What are the symptoms of Addison's disease ( ALD )?
