GenFam

GenFam performs gene family-based classification and functional enrichment analysis to identify overrepresented gene families in genome-scale gene lists generated by high-throughput sequencing (HTS) studies, with emphasis on plant genomes.

Key Features:

• Gene Family Annotation and Classification: A computational approach to annotate, classify, and perform enrichment on gene sets based on gene family associations to simplify identification of candidate gene families and related genes.
• Comprehensive Database: An integrated database covering 384 unique gene families across sixty plant genomes to support family-level analyses across diverse species.
• Comparative Case Studies: Four comparative case studies involving plant species from different clades and families demonstrating the method's robustness and comprehensiveness.
• Customizable Statistical Parameters: Support for selection among various statistical enrichment tests and multiple testing correction methods to tailor analysis parameters.
• Gene-family–based Enrichment: Enables enrichment analyses based on gene family membership as an alternative to Gene Ontology (GO)-based approaches for nuanced functional interpretation.

Scientific Applications:

• Functional characterization of plant genes: Use gene family associations to infer functions and prioritize candidate genes from genome-scale datasets.
• Interpretation of HTS-derived differential expression lists: Identify overrepresented gene families in lists of differentially expressed genes from high-throughput sequencing experiments.
• Comparative plant genomics: Compare family-level enrichment across species and clades to reveal conserved or lineage-specific functional patterns.

Methodology:

Genes are classified into predefined gene families and statistical analyses are applied to user-defined gene lists to identify overrepresented gene families.
