Best Answer

Yes.

It is possible to carry the gene(s) for a hereditary disease without the disease ever being expressed. The chance of a child inheriting the disease, rather than just being a carrier like its parents, depends on the disease and on whether one or both parents has the gene.

A genetic counselor or clinical geneticist would be able to give the chances for a child having a specific disease.

What diseases are hereditary?

The term "hereditary disease" is usually used to refer to diseases which have a high likelihood of being inherited in one's offspring, usually by a predictable probability. For example, if you have Huntington's disease, there is a 50-50 chance that your child will have it. On the other hand, almost all diseases are more probable in the offspring of a person who has them than in the offspring of a person who does not. Thus, a tendency to develop a medical condition can run in families. Such conditions, however, are not usually referred to as hereditary diseases. For example, if you have allergies to pollens, then your children are more likely to develop such allergies, than are the children of your friend who does not have allergies.
