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]
