Background

One of the key goals in the postgenomic era is the elucidation of the mechanisms underlying the relationship between genotype and phenotype. In particular, understanding how human genetic and somatic variations are associated with diseases is still an open problem and its solution is a crucial issue for exploiting the possibilities offered by the modern sequencing techniques in the framework of precision and personalized medicine. The increasing amount of data generated by the sequencing initiatives calls for accurate and reliable computational approaches to predict the impact of mutations on the phenotype, and possibly for methods to correlate them with diseases. From the experimental point of view, disease-causing variants are supposed to directly affect protein function, protein stability as well as the kinetics and thermodynamics of protein-protein recognition, and robust validation at the molecular scale is necessary. This approach can be of invaluable help in facing new challenges such as the fast development of effective vaccines.

Progress in computational and experimental research and their interplay in the annotation and interpretation of protein variants to detect pathogenetic variations and analyze their effect will be discussed in this Research Topic. A major theme in this issue is to discuss how the computational and experimental analysis of non-synonymous Single Nucleotide Polymorphisms (nsSNPs) in the human genome at a structural and molecular level may help to predict the risk of developing specific diseases, as well as the susceptibility to environmental factors and the personal response to specific drugs.

Authors whose research follows within this area are welcome to contribute to this Research Topic. Original articles and up-to-date reviews will be considered for publication. Areas to be covered in this Research Topic may include, but are not limited to:
• The effects that disease-associated protein variants induce on thermal and thermodynamic stability and 3D structural properties
• The changes induced by disease-associated protein variants on enzyme functions and kinetic properties
• The effects of disease-associated protein variants on the kinetics of protein-protein interactions as well as on protein networks at the system-level
• The changes induced by protein variations on the interactions with specific pharmacological ligands
• The annotation of nsSNP and disease-associated variants in genetic and multifactorial diseases
• The advantages and limitations of current computational methodologies based on the prediction of the impact of protein variations on protein stability and their potential pathogenicity
• Computational approaches to predict the impact of genetic variations on diseases through the analysis of their effects on the protein functions

Keywords: Computational, Experimental, Protein, Variant, Precision Medicine

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
