Unraveling Vitiligo’s Mysteries
A study has found slight variations from normal in 10 genes associated with the body’s immune system in people with vitiligo, confirming this mysterious disease’s autoimmune nature and pointing to a better understanding that may one day lead to more personalized treatment for vitiligo patients.
Vitiligo is a complex disorder in which patches of the skin’s melanin, or pigment, disappear, leaving white areas on the skin and even hair. Autoimmune disorders are those involving the body’s immune system attacking healthy cells in the body. The findings suggest vitiligo involves multiple pathways, meaning the exact triggers are complicated, involving both genetics and environmental factors together. This implies cures may be complicated and may involve treatments geared to the individual.
