Can I Pass Alopecia on to My Children?

It is possible, but not likely, for alopecia universalis to be inherited. Most children with alopecia universalis do not have a parent with the disease, and the vast majority of parents with alopecia universalis do not pass it along to their children.

Alopecia universalis is not like some genetic diseases in which a child has a 50-50 chance of developing the disease if one parent has it. Scientists believe that there may be a number of genes that predispose certain people to the disease. It is highly unlikely that a child would inherit all of the genes needed to predispose him or her to the disease.

Even with the right (or wrong) combination of genes, alopecia universalis is not a certainty. In identical twins, who share all of the same genes, the concordance rate is only 55 percent. In other words, if one twin has the disease, there is only a 55 percent chance that the other twin will have it as well. This shows that other factors besides genetics are required to trigger the disease.
