Is vitiligo caused by inheritance?
Chances are minimal if at all
Hello and welcome back to healthcaremagic
I am Dr. Kakkar. I have gone through your query.
Vitiligo is apparently caused by inheritance of multiple causal genes simultaneously, possibly in different combinations in different people, plus exposure to environmental risk factors or triggers that are not yet known. Therefore, no one can accurately predict the chances that the girl in question would get vitiligo in future. In fact I would say that, no one can predict who gets vitiligo and in most of the cases there is no family history.
Approximately 20% of vitiligo patients have a family member with the same condition (the rest 80% don't).
However, only 5% to 7% of children will get vitiligo even if a parent has it.
Moreover, half of those with vitiligo develop it before the age of 20, and about 95% before age 40.
Therefore, as the girl does'nt have vitiligo the chances are she never will.
