热门问题：白癜风是遗传性疾病吗？Is vitiligo genetically transmitted disease?

热门回答：         
Vitiligo is an autoimmune condition whose cause is unknown as of yet.

白癜风是一种自身免疫性疾病，其病因尚不清楚。

IT IS NOT an infectious diseases, i.e. it will not be transmitted by direct/indirect contact.

它不是传染病，即不会通过直接/间接接触传播。

If that was the case, then my complete family would have Vitiligo today, and given the fact that it is just I who has it since the past 23 years while none in my family, friend circle or acquaintances have it, proves my point.

如果是这样的话，那么我的整个家庭今天都会患白癜风，考虑到过去23年来只有我患白癜风，而我的家人、朋友圈或熟人中没有人患白癜风，这就证明了我的观点。

However, there have been cases, where Vitiligo has been found to be hereditary.

然而，也有一些白癜风被发现是遗传性的。
