If you have autosomal recessive hemochromatosis (types 1-3), other family members should have testing as well. Your parents are both likely unaffected carriers of the condition, meaning each of them has one working copy and one non-working copy of the gene. Daughters, sons, sisters, brothers, uncles, and aunts may also be at risk to be carriers or affected. Carriers have one working copy of the gene and one nonworking copy. Carriers therefore have a risk of having a child with hemochromatosis if their partners are also carriers.
If you have autosomal dominant hemochromatosis (type 4), your sisters, brothers, parents, and children have a 50% chance to also have hemochromatosis. Your aunts, uncles, and grandparents have a 25% chance to also have type 4 hemochromatosis.
