Is it true that genetics may play a part in vitiligo?

Most experts believe that there is a genetic base to vitiligo which leads to susceptibility. Though not common, there are enough family's where vitiligo is seen in more than one member, that a genetic theory can be established. Though no one else in your family may show signs of vitiligo, it is still possible that it is passed on genetically. The most likely reason for this is that more than one gene is responsible for the development of vitiligo. It is a combination of genes that may prove to be the critical factor and it may also need some stimulus to cause the condition to onset.
