Drmwarfism in Sci-Fi

Had a thought a little while ago. How would your sci-fi world handke dwarfism?

For instance, would they even exist? Would DNA for dwarfism characteristics be removed through genetic engineering? Or would bodies be physically altered through surgeries and/or prosthetics? Would living quarters be altered on a soace station to suit them or would they be altered instead? How would they be treated? Would there be a colony made up of such peoples exclusively or have a higher concentration of dwarfism? What could such a colony produce?

And yes, I realize there are many different types of dwarfism with different classifications and causes. This is more of a thought exercise. I just haven't read many sci-fi books that have characters with dwarfism and now I'm wondering if I should include that in one of the novels I'm working on.
