Pathway/Functional Analysis
The results of many "standard" bioinformatics analyses are
usually lists of variants, transcripts, or genes and some statistic -
e.g., a gene name, fold change, and multiple-testing-corrected P-value
for a gene expression study; or a SNP, odds ratio, and p-value for an
association to a disease phenotype from a genetic association study.
Most of the time, these "gene lists" are derived from tests that
examine a single genetic variant or over/under-expression of a single
gene at a time between two conditions (case vs. control, wild type vs
mutant).
However, the prevailing view is that complex phenotypes are not
the result of a single gene but reflect abnormalities in the entire
cellular network that links tissues and organ systems. A better
understanding of how genetic variants, gene expression, DNA binding,
and DNA methylation at multiple loci throughout the genome work
together to influence the presentation of a complex phenotype may lead
to discovery and characterization of unknown biological
processes.
This is the basis for "pathway analysis" or functional
annotation - putting lists of genes into biological context. This is an
incomplete list of these kinds of analysis the core can assist
with.
- Functional annotation
-
- Gene ontology
- KEGG (pathways)
- Overrepresentation analysis
-
- Gene ontology
- KEGG (pathways)
- Ingenuity Pathway Analysis
-
- Canonical pathways
- Biological networks
- Upstream transcription factors that influence your gene's expression
This list will grow over the coming months. If you would like to become an early adopter and receive core services at reduced or no cost, please fill out a consult request form and email Stephen Turner for more information.
