Vitiligo is a primary, limited or generalized pigmentation loss of the skin and mucous membranes. The prevalence in the population is relatively high, with an estimated 1% to 2 of the population suffering from vitiligo. The age ranges from infancy to old age. Clinical evidence of familial clustering of vitiligo patients can be seen. There are three consecutive generations, or fathers and children, mothers and children with the disease. It is also possible to see monozygotic twins in which both of them develop vitiligo. This kind of situation indicates that vitiligo has family inheritance. The genetic inheritance of vitiligo does not follow the autosomal single locus gene pattern, now research can see that the vitiligo phenotype is controlled by recessive genes at three or four loci on the autosomes. And vitiligo patients have defective melanocytes that undergo aberrations such as broken pieces and monosomy breaks. In addition to the causes of vitiligo are neuropsychiatric factors, melanocyte self-destruction, immune theory.
The most important thing is that you can get the most out of your life. The people with the disease can be related or unrelated. Vitiligo does not have these characteristics. Vitiligo patients are familial gathering, so vitiligo patients contacting normal people around will not spread vitiligo.
