Animal-ImputeDB

Animal-ImputeDB provides reference panels and genotype imputation resources for 13 animal species to support genotype imputation in genome-wide association studies (GWAS) and genetic improvement programs.

Key Features:

• Extensive Reference Panels: High-quality reference panels constructed from approximately 400 million single nucleotide polymorphisms (SNPs) derived from 2,265 samples across multiple animal species.
• Genotype Imputation: Computational prediction of unobserved genotypes to increase SNP density for studies using low-density SNP arrays.
• Integration of Imputation Tools: Incorporation of two widely-used imputation tools for performing genotype imputation using the reference panels.
• Aggregation of Genomic Data: Compilation of genotype data and whole-genome resequencing data from multiple studies and databases to build robust reference panels.
• Cross-Species Coverage: Reference panels and imputation resources covering 13 diverse nonhuman animal species.

Scientific Applications:

• Genome-Wide Association Studies (GWAS): Increasing SNP density through imputation to enhance detection of associations between genetic variants and phenotypic traits.
• Genetic Improvement Programs: Enabling more detailed genetic analyses to inform selection and breeding decisions in livestock and other animals.
• Conservation Genetics: Supporting analyses that inform preservation of genetic diversity and breeding strategies for endangered species.

Methodology:

Creation of a computational pipeline to process diverse raw data types and aggregate genotype and whole-genome resequencing data, construction of reference panels (≈400 million SNPs from 2,265 samples across 13 species), and integration of two widely-used imputation tools for genotype imputation.
