Adrenoleukodystrophy (ALD) is an inherited genetic disorder that affects the nervous system, adrenal glands, and white matter of the brain. It is caused by mutations in the ABCD1 gene, which is passed down from parent to child. Symptoms of ALD can vary from mild to severe, but generally include vision and hearing loss, seizures, difficulty walking, and difficulty with intellectual and motor skills.
ALD is usually diagnosed in childhood, and those with the disorder may experience a gradual decline in neurological and physical functioning. In some cases, the disease can be fatal if not treated. Treatment for ALD can include medications, diet, physical therapy, and stem cell transplantation.
The genetic mutation responsible for ALD is passed down from parent to child in an autosomal recessive manner. This means that a child must inherit two copies of the mutated gene, one from each parent, in order to develop the disorder. If both parents are carriers of the mutated gene, there is a 25% chance that their child will be affected by ALD.
In summary, ALD is a genetic disorder that is passed down from parent to child in an autosomal recessive manner. Symptoms vary from mild to severe, and if left untreated, can be fatal. Treatment for ALD can include medications, diet, physical therapy, and stem cell transplantation.
