G-tract-AG Motifs: A Genomic Signature Regulating Splicing and Disease

Research from 2026 investigates a mammalian genomic signature, G-tract-AG motifs, which regulate transcriptome integrity and diversity. The dataset includes supplementary files analyzing approximately 9,000 G-tracts within human genes disrupted by variants from the Genotype-Tissue Expression project. It provides a framework for functionally annotating non-coding region variants associated with diverse traits and genetic diseases.

Use Cases

• Identifying candidate functional non-coding variants based on G-tract-AG motif disruption.
• Investigating the role of G-tracts in stalling the second transesterification step of splicing.
• Annotating cis-splicing quantitative trait loci (sQTLs) from projects like GTEx.
• Studying the generation of novel transcript isoforms through variant-induced splicing changes.

Strengths

• Provides mechanistic insights into a widespread genomic signature, with analysis of ~9,000 G-tracts in human genes.
• Dataset is openly available under a CC-BY-4.0 license, facilitating reuse and redistribution.
• Cross-platform presence on figshare indicates established sharing and potential for community use.

Limitations

• Column names and a precise row count are not provided, limiting understanding of the dataset's internal structure.
• The dataset consists of supplementary files (e.g., gels, images, tables) rather than a primary, unified analysis-ready table.
• Metadata for organization and detailed data collection methodology is incomplete.
