UCSC Genome Browser database

UCSC Genome Browser provides integrated visualization and access to genome assemblies, annotations, and diverse genomic data tracks to support analysis of genomic structure, variation, and regulation.

Key Features:

• Data Visualization: Supports Hi-C heatmap displays for chromatin interaction data, phased family trio displays for VCF files, and multiple track visualization modes to represent diverse genomic information.
• Genome Annotations: Aggregates gene annotations from GENCODE, NCBI RefSeq, and Ensembl Genes.
• Data Tracks: Includes ENCODE registry of candidate cis-regulatory elements, promoters from the Eukaryotic Promoter Database, NCBI RefSeq Select, and MANE (Matched Annotation from NCBI and EMBL-EBI).
• SARS-CoV-2 Reference: Provides a specialized genome browser and annotation tracks for the SARS-CoV-2 RNA reference assembly.
• Data Access and Formats: Provides sequence and annotation downloads in formats including JSON via an API, supports FTP table downloads, and exposes current table descriptions and formats via the Table Browser "describe table schema" function.
• Annotation Updates: Maintains and updates annotation databases to incorporate new genome assemblies and annotation sets.

Scientific Applications:

• Comparative Genomics: Enables comparison of genome assemblies and annotations across species and builds.
• Gene Expression and Regulation: Supports analysis of promoters, regulatory elements, and expression-related tracks such as ENCODE cCREs.
• Variant Interpretation: Facilitates interpretation of genetic variants using integrated annotation tracks and RefSeq/MANE mappings.
• Chromatin Interaction Analysis: Enables analysis of chromatin conformation data through Hi-C heatmap displays.
• Family-based Phasing: Supports phased family trio analysis for VCF-based variant phasing and inheritance studies.
• Pathogen Genomics: Provides SARS-CoV-2 reference annotation tracks for viral genome analysis.

Methodology:

Implements Hi-C heatmap and phased trio displays for VCF, integrates annotations from GENCODE/NCBI RefSeq/Ensembl, imports ENCODE cCREs, Eukaryotic Promoter Database promoters, NCBI RefSeq Select and MANE, hosts a SARS-CoV-2 RNA reference assembly browser, and provides data downloads via JSON API and FTP with table schema descriptions via the Table Browser.
