There are chromosomes in the human body, the chromosomes of the fetus come from the parents, the chromosome cell nucleus contains the material of genetic information, some studies believe that part of the vitiligo is due to the autosomal dominant gene abnormality. If one of the parents has vitiligo, then there is a possibility that this abnormal gene will be given to the child and hereditary vitiligo will be formed, but the chance of this is very low only 10.8%-20%. It is mainly caused by acquired factors, such as bumping, burning, mosquito bites, insect bites and other factors, and may also be related to mental stress. So patients with vitiligo can get married and have children, do not have too much pressure, pay attention to rest, usually pay attention to temperament.
