The scientific studies available to date did not show the certainty of the hereditary attachment of vitiligo.
There are a number of published studies and others that continue to be possible relationship between genetic factors and family history in predisposition to vitiligo.
Vitiligo is an acquired skin depigmentation that occurs in approximately 1% of the population. It is the result of an autoimmune process against melanocyte cells, responsible for skin pigmentation.
The precise cause of the disease is still unknown. Cellular immunity plays an important role in the development of the disease. Thus, the person's body starts producing antibodies that fight melanocytes and destroys them, the affected region is depigmented, with a lighter color compared to the rest of the skin.
Science still needs to move forward with future discoveries, the available knowledge evidences possible relationship to the hereditary factor, but without absolute certainty.
