Is Vitiligo genetic
There are several theories, but the cause of vitiligo is not fully known.
One thesis of some substance is that individuals with vitiligo initiate antibodies that, turn upon them and destroy their own melanocytes, instead of protecting them, the specific cells that manufacture the pigment melanin that colors their skin.
Another thesis is that the melanocytes somehow strike and demolish themselves. Finally, few people with vitiligo have revealed that a single incident such as an episode of emotional distress or severe sunburn seem to have provoked their vitiligo.
Events of this nature, however, may simply be an accident and have not been scientifically proven to cause vitiligo.
Are there many people with vitiligo?
About one to two percent of people in the world, or forty to fifty million people, has vitiligo. In the United States alone, two to five million people have the disorder.
Vitiligo is initiated in 95% of people it before forty years of their age. The disorder affects both sexes and all races are equally affected.
Vitiligo may run in families and be hereditary. Parents of children who have the disorder are more prone to get vitiligo. However, even if a parent has vitiligo most children will not get vitiligo, and many people with vitiligo do not have a family history of vitiligo.
Vitiligo is associated with a sizable number of inherited disorders. To demonstrate, they include:
Albinism of the ocular type
Autoimmune Polyendocrinopathy Syndrome
Achalasia and Congenital deafness with vitiligo
Dyschromatosis symmetrica hereditary
Familial histiocyctic reticulosis
Progressive hemifacial atrophy
Progressive vitiligo with psychological retardation and urethral duplication
The syndrome of spastic paraparesis vitiligo and Schmidt syndrome
Characteristic facies and Premature graying
The copious quantity of genetic diseases associated with vitiligo clearly indicates the fact that there are numerous genes which generally control the development and safety of the melanocyte.
