How is X-linked adrenoleukodystrophy inherited?
X-linked adrenoleukodystrophy is inherited in an X-linked manner, because the ABCD1 gene is located on the X chromosome. Women who are carriers for X-linked adrenoleukodystrophy have a 50% chance of passing the changed ABCD1 gene to each of their children. If a daughter inherits the change, she too will be a carrier, or mildly affected. If a son inherits the change he will likely exhibit full symptoms of X-linked adrenoleukodystrophy. Men who have X-linked adrenoleukodystrophy will not pass their genetic change on to any of their sons, but all of their daughters will be carriers.
