Yes, depending on the type of adrenoleukodystrophy (ALD) a person has, they may be able to have children. ALD is an inherited disorder caused by a mutation in the ABCD1 gene, which is a recessive gene. There are three types of ALD: childhood cerebral ALD, adrenomyeloneuropathy, and Addison's disease.
For those with childhood cerebral ALD, the chances of having children are very low as this type of ALD is usually fatal in a few years. In this case, a carrier wouldn’t be able to pass the gene onto their children.
For those with adrenomyeloneuropathy, the chances of having children are higher. In this type of ALD, the symptoms may not appear until the person is in their 30s or 40s, and the disease can affect fertility. In this case, a carrier would be able to pass the gene onto their children, and those children would have a 50% chance of inheriting ALD.
For those with Addison’s disease, the chances of having children are higher. Although Addison’s disease is caused by a mutation in the ABCD1 gene, it does not usually cause any fertility problems. A carrier would be able to pass the gene onto their children, and those children would have a 50% chance of inheriting ALD.
Overall, whether or not someone with ALD can have children depends on the type of ALD they have. If they have a milder form of ALD, such as Addison’s disease, then they may be able to have children. However, if they have a more severe form of ALD, such as childhood cerebral ALD, then they may not be able to have children.
