I have vitiligo: will my children have vitiligo, too?

If you have vitiligo, it’s natural to worry about your children. While there is a genetic component, vitiligo is not a straightforward hereditary disease like eye color or height.

The Probability: Odds Are in Their Favor

The most important takeaway is this: The vast majority of children born to parents with vitiligo will never develop the condition.

  • The 5% Rule: Children of a parent with vitiligo have about a 5–6% chance of developing it. While this is higher than the 1% risk in the general population, it means there is a 94–95% chance they will not.
  • The Twin Study: Even among identical twins—who share 100% of the same DNA—there is only a 23% chance that both will have vitiligo. This is the strongest evidence we have that DNA is only one part of the story.
  • Global Patterns: Around 20% of people with vitiligo have at least one affected relative. In white, Indo-Pakistani, and Hispanic populations, the frequency of vitiligo in first-degree relatives (parents, siblings, or children) holds steady at approximately 7%.

The "Complex Genetic" Puzzle

Vitiligo is a "complex genetic disorder." Think of it as a puzzle with dozens of pieces. Your child might inherit some of the "genetic pieces" from you, but unless they also encounter the specific environmental triggers the disease will likely never be switched on.

The Bottom Line

Having vitiligo is not a "guarantee" for your children; it simply means they carry the potential. Because non-genetic factors play such a massive role, the majority of children born to parents with vitiligo live their entire lives with their pigment fully intact.

If your family has a history of other autoimmune conditions (like thyroid issues or alopecia), the risk can be slightly higher, and a consultation with a dermatologist can offer more tailored insight for your specific family history.
