Total number of the Alu-inserted gene lists from TranspoGene database

Insertion type	Alu-inserted genes (n)
All insertion types*	13,534
Exonized type	812
Exonic type	1593
Intronic type	13,245
Promoter type	557

We obtained the lists of human genes with at least one Alu elements from the TranspoGene database. The lists can be categorized into five types of Alu insertions: exonized, exonic, intronic, promoter, and all insertion. Note that multiple Alu elements can be inserted within a single gene with different insertion types. Therefore, the total number of Alu-inserted genes is less than the sum of the exonic, exonized, intronic, and promoter types. These lists of Alu-inserted genes were used for subsequent overlap analyses with differentially expressed genes (DEGs) in ASD
