A representative gene network showing overlap of some neurologically relevant genes among 3 discordant autistic twin sets using Ingenuity Pathways Analysis software. Genes shown in yellow represent overlap of differentially expressed genes in 2 or more sets of twins, whereas the red and green nodes correspond to genes that are up- or down-regulated, respectively, in only 1 twin set. The expression cutoff was set at log2(ratio) = ± 0.58 for each twin set. The 12 genes marked by "#" are known to be involved in nervous system development and function.
