  • Introducing ProtVar: A Web Tool for Contextualizing and Interpreting Human Missense Variation in Proteins

    On May 24, EMBL's European Bioinformatics Institute (EMBL-EBI) will unveil ProtVar, an innovative web tool designed to assist users in comprehending and interpreting missense variations in human proteins. By integrating various databases and incorporating cutting-edge analyses, ProtVar offers a streamlined approach to understanding the impact of genomic variation on protein structure, function, and ultimately human health and disease.

    Understanding Missense Variation
    Missense variation refers to a single nucleotide change in the genome that results in the substitution of one amino acid for another within a protein. This type of variation can have intricate implications for normal biological function. Gaining insights into how missense variations manifest in proteins is crucial for identifying potential drug targets and developing novel therapeutics. However, achieving this understanding necessitates the synthesis of diverse datasets in a coherent manner.

    The Power of ProtVar
    ProtVar harnesses the power of data integration by combining information from UniProt, PDBe, Ensembl, and other databases, while also incorporating analyses from Open Targets. This comprehensive approach allows users to seamlessly navigate through genomic data, protein sequences, functional annotations, and structural insights. By leveraging ProtVar, researchers can swiftly identify and evaluate the potential effects of missense variations on human health and disease.

    Deciphering Missense Variation
    ProtVar empowers users by providing amino acid-specific information, enabling the investigation of each variant independently and facilitating comparison with known variations occurring at the same amino acid position. Clinical geneticists can leverage this functionality to identify and prioritize variants that are most likely associated with disease in their patients.

    Moreover, ProtVar integrates data derived from AlphaFold2 algorithms, generated as part of the Open Targets project. This information encompasses predicted impacts on protein stability, as well as whether the variant position is likely to be involved in a protein-protein interface or a small molecule binding site. Researchers can visualize variant positions in an annotated structural context, aiding in the understanding of missense mutations, particularly within drug-binding pockets.

    Enhancing Speed and Accessibility
    ProtVar not only offers advanced algorithms but also ensures ease of access and rapid delivery of relevant, up-to-date data. This significantly reduces the time and effort required for data analysis, saving researchers valuable hours or even days of work. Furthermore, ProtVar's impact on our understanding of genetic variation and its role in disease and health is profound, and the tool will continue to evolve with updates and the addition of new features in future releases.

    Streamlined Data Interpretation
    ProtVar simplifies data interpretation by enabling users to input genomic coordinates, protein positions, or variant IDs (e.g., dbSNP). This flexibility provides a substantial advantage over similar resources, eliminating the need for manual information mapping. The tool also includes precomputed mappings of the human proteome across different genome assemblies, ensuring researchers can access the required information with a single click.

    Applying ProtVar
    ProtVar caters to a wide range of audiences, including clinical geneticists involved in diagnosing patients, researchers in drug discovery, virologists, and scientists studying the relationship between protein sequence, structure, and function. The tool offers a reliable link between genomic coordinates and protein positions, making it invaluable for exploring and interpreting missense variants that may have relevance to disease.

    Conclusion
    ProtVar represents a transformative web tool that expedites the interpretation of coding variations, providing rapid analysis and insight into the consequences of amino acid substitutions. Its impact extends to various domains, from clinical genetics to drug discovery. ProtVar's accessibility, speed, and integration capabilities offer a valuable resource to the scientific community, facilitating a deeper understanding of genetic variation and its implications for human health. ​Access the new ProtVar web tool.

    Exploring the Dynamics of the Tumor Microenvironment
    by seqadmin




    The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

    Exploring Human Diversity Through Large-Scale Omics
    by seqadmin


    In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
