• Notes on use

  • All gene-sets have good quality with respect to enrichment in neuropsychological functions and phenotypes

  • ExpHsBr and PhMmAll are the ones I found of higher quality when overlapping with my autism gene-set analysis results

    • A sizable number of genes inPhMmAll may have neurological system development phenotypes at relatively early stages (e.g. neural tube formation)

  • PhHsPsy probably includes several genes from candidate gene studies, but is otherwise of good quality

  • The distinction between PhHsPsy and PhHsDev is a bit loose, these two gene-sets could be collapsed

  • PhHsMsc is quite heterogeneous, and its neurovascular and neurodegenerative auto-immune components are probably source of bad candidates for researchers working on autism, schizophrenia or ADHD

  • PhMmAll is not completely unbiased, as investigators will make KO mouse models for genes of interest

  • ExpHsBr may be partially biased towards well characterized genes

• Gene Ontology Neurological Gene-sets Rws

Details

• ID System: human Entrez-Gene

• Documentation

  • Manually selected Gene Ontology terms

• Notes on use

  • I removed sensory receptors (e.g. olfactory receptors) from Human Nervous System Process, otherwise they would be the majority of genes in this gene-set

  • Nervous System Process includes interesting stuff like Neuron differentiation and Axon guidance

  • These gene-sets depend on Gene Ontology annotations; genes that are poorly annotated are likely to be covered by neurological phenotypes or brain-specific expression gene-sets

Neurological Pathways as Gene-sets

Last update: March/April 2011
Text files

• Neurological Pathways (collapsed)

R Workspace

• Neurological Pathways Rws (by pathway)

Details

• ID System: human Entrez-Gene

• Documentation

  • Manually selected pathways (Reactome, KEGG, Biocarta, NCI)
• Breakdown by pathway only in the R ws

R ws Object Structure (common)

• each ws has only one object: a list with two slots:
  • $gs2gene: list
    • names: gene-set IDs
    • slot content: genes (character vector)
  • $gs2name: character vector
    • names: gene-set IDs
    • values: genes
