Gene Set Enrichment Analysis (GSEA) analysis of two significantly enriched classes of genes: nervous system development and neurodegenerative diseases. (A) Enrichment plot for a category nervous system development that includes 300 genes. (B) Normogram for 111 core-enriched genes classified in nervous system development. (C) Enrichment plot for a category of neurodegenerative diseases that includes 34 genes. (D) Normogram for 14 core enriched genes classified in neurodegenerative diseases. Individual genes are listed in Additional file 5. Increased expression (red); decreased expression (blue).
