Thanks Bhogaraju Anand . I am looking for a good and huge dataset for research purpose. This one is too small and not good for what I am looking for. Although great thanks for the efforts. I'll keep looking deeper.

Have a look on SFARI gene database maybe !

No data base on that but would sure be an interesting study!

Autism detection and gene databases are different. As previously suggested you can request authors of meta-analysis on autism. Also Cochrane database can help you and some of it is open source.
