For a psychological disorder, schizophrenia has a very large genetic component - up to 48% in MZ twins, as you know. It's pretty maladaptive to have schizophrenia so why has it persisted in the genome?
Here is an interesting read about schizophrenia and evolution. It's hard to get our head round the fact that schizophrenia may actually be adaptive in some form or other. There are various evolutionary explanations and the article explains that the genes for SZ may be coupled to other, more positive traits, like intelligence.
Thanks to Jack C-J for suggesting the article. Anyone should feel free to contribute to the blog.
