in the network analyses for genes and exons was 30 and 5, respectively. Network connectivity for both coexpression and cosplicing were calculated as described elsewhere (Iancu et al. 2015). Genes in the top 50% for both coexpression and cosplicing connectivity (see below) were used for further analysis (7545 genes). The expression data are available via NCBI Gene Expression Omnibus (accession number GSE65950, ID: 200065950).
