Your Question

If a couple has a child with Krabbe leukodystrophy, what is the likelihood of having another child with the condition?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

How is Krabbe leukodystrophy inherited?

Krabbe leukodystrophy is inherited in an autosomal recessive manner. If both parents are carriers (each having one working copy of the gene and one non-working copy), each child that they have has a 25% chance (1 in 4) of being affected (having the condition), a 50% chance (1 in 2) of being an asymptomatic carrier (like each parent), and a 25% chance of being unaffected (not having the condition) and also not being a carrier. If a sibling of a child with Krabbe leukodystrophy is already known to be unaffected, the chance of him/her being a carrier is 2/3.[1]
