Here is an interesting post about the influence of genes on dyslexia:
Faulty Gene “is the link to dyslexia”
Of course, I think this view of the world misses the point really.
We know that our genes have a big influence on these things.  So to find an influencing gene is interesting but essentially useless. Only a madman would subscribe to gene alteration therapy unless your life was threatened without it.
What interests me more is how to help someone, given the genes that they have.  That is what Easyread is all about.
