BioBin

BioBin performs rare variant association analysis by collapsing genetic variants into biologically informed bins using prior knowledge from integrated biological databases.

Key Features:

• Biological Variant Binning: Aggregates sequence variants into bins defined by functional regions, evolutionarily conserved regions, regulatory regions, genes, pathways, and other biological categories using integrated biological knowledge.
• Integrated Knowledge Database: Utilizes a prebuilt database compiled from multiple publicly available biological databases to guide variant binning.
• Rare Variant Association Testing: Performs statistical association testing between binned rare variants and phenotypic traits or diseases.
• Configurable Binning Algorithm: Supports customizable analyses through configurable binning strategies and analytical parameters.

Scientific Applications:

• Rare Variant Association Studies: Identifies associations between aggregated rare variants and complex traits or diseases.
• Population Genomic Analysis: Detects differences in rare variant burdens across populations such as Yoruba (YRI) and European descent (CEU) individuals in the 1000 Genomes Project.
• Functional Variant Burden Analysis: Evaluates rare variant distributions across genes, pathways, regulatory regions, and conserved genomic elements.

Methodology:

BioBin collapses sequence variants into biologically defined bins using a database of prior biological knowledge and performs statistical association testing on aggregated rare variants.
