In some cases vitiligo seems to be inherited and run in families, with children whose parents have vitiligo being at increased risk of developing the condition themselves.
The frequency of vitiligo among first degree relatives in white, Indo - Pakistani, and Hispanic populations is 7.1%, 6.1%, and 4.8%, respectively. Identical twins with identical DNA have only a 23% chance of developing vitiligo, suggesting a significant non-genetic component in the disease.
