What are the risks to the children of a man with X-linked adrenoleukodystrophy?
Males have one X and one Y chromosome. All the daughters of a male with X-linked adrenoleukodystrophy will inherit the ABCD1 gene that isn't working properly because that is the only X chromosome a male has to pass on. That daughter would most likely inherit a normally functioning ABCD1 gene from her mother, and therefore she would be a carrier. Most carriers do not show symptoms of the condition. If they do show symptoms, these symptoms are less severe than those of a male. Sons of a male with X-linked adrenoleukodystrophy will have no risk of inheriting the condition, because they do not receive their father's X chromosome, only his Y chromosome.
