 Gene set enrichment analysis

Gene Set Enrichment Analysis (GSEA) is a computational method used to identify whether a predefined set of genes shows statistically significant differences in expression under different biological conditions, such as diseased versus healthy states or various treatments. The goal of GSEA is to determine whether genes that share common biological functions, chromosomal locations, or regulation are overrepresented (enriched) within a specific group of genes that have been identified as being significantly different between conditions.
