Could women with vitiligo still have healthy babies?

Yes: Vitiligo (v) is an autosomal dominant disorder with variable penetrance (some worse than others).A mother can pass the gene to her kid or pass the normal gene with 50/50 chance per conception. Children acquiring the v gent would eventually show some patches as they age & the baby with the normal gene would be unaffected. Other than the skin issue, the babies are normal.
