Can Cafe au lait and vitiligo be passed to the children?

I am 25 years old, I have Cafe au lait spots along my right arm, neck and back I had these spots on my arm since my birth and got growing until I reached adulthood... My mother have small spot that is hardly noticable on her arm also my sister. My feionce is having Vitiligo since the age of 13 I am not sure to which degree the vitiligo is spread on his skin, but non if his close relatives are having it...
I am worried about the chance of passing these skin issues to our future children. Would our children have a high chance of getting these issues since I am having Cafe au lait and he is having Vitiligo?

Cafe-au-lait spots themselves do not cause health issues. Having multiple spots has been linked to a number of genetic conditions. We recommend that you meet with a dermatologist for evaluation.

Vitiligo is a separate skin condition. This skin disorder is multifactorial, which means that both genetic and non-genetic factors contribute to developing this condition. We know that vitiligo runs in some families. In these families, there are typically multiple affected people in different generations.

We recommend that you meet with a genetic counselor who can review your personal and families histories in order to provider a more specific and accurate risk assessment. A genetic counselor can be found at the National Society of Genetic Counselor website or through companies like mine, AccessDNA.
