Gephebase

Gephebase catalogs genotype–phenotype relationships across Eukaryotes by compiling curated, literature-derived gene and mutation associations linked to phenotypic variation.

Key Features:

• Scope: Covers genotype–phenotype relationships across Eukaryotes including animals, plants, and yeasts.
• Evidence types: Records associations supported by linkage mapping, association mapping, and candidate-gene approaches.
• Content size: Contains over 1,700 curated entries each detailing an allelic variation at a specific gene and its correlated phenotype.
• Variant-level detail: Entries include molecular details of mutations and allelic variants.
• Annotations: Entries are annotated with taxonomic classifications and bibliographic references.
• Queryable attributes: Annotations cover features such as transposable elements, taxa (e.g., snakes), and traits (e.g., carotenoid content) and support Boolean-queryable parameters.
• Exclusions and related resources: Excludes human clinical traits and laboratory aberrant mutant phenotypes and references related resources such as OMIM, OMIA, and the Monarch Initiative.
• Meta-analysis support: Structured entries enable meta-analyses to identify global trends in genotype–phenotype associations.

Scientific Applications:

• Comparative and evolutionary genetics: Analyze genetic bases of phenotypic diversity across species and populations.
• Target identification for crop improvement: Identify genes and alleles with potential utility in crop breeding.
• Pest control: Identify genetic targets relevant to pest management strategies.
• Bioconservation: Inform conservation genetics by linking allelic variation to phenotypic traits of conservation concern.
• Genetic diagnostics: Support identification of candidate genes for diagnostic applications in non-human organisms.
• Meta-analysis of global trends: Aggregate curated cases to detect broad patterns in genotype–phenotype relationships.

Methodology:

Curated extraction of genotype–phenotype associations from primary scientific literature, with entries accepted when supported by linkage mapping, association mapping, or candidate-gene evidence and annotated with allelic, molecular, taxonomic, and bibliographic information.
