Background of the Study :
The accurate annotation of genomic variants is a critical step in the interpretation of sequencing data, particularly in the context of precision medicine and genetic research. This study focuses on the design and implementation of an automated genomic variant annotation tool that can streamline the process of identifying clinically relevant mutations. At Federal University, Wukari, Taraba State, the project aims to integrate various databases and bioinformatics algorithms into a cohesive platform that facilitates rapid and accurate variant annotation (Olu, 2023). By automating the annotation process, the tool will reduce the time and expertise required to interpret genomic data, thereby increasing the efficiency of genetic research and clinical diagnostics. The system will employ natural language processing, machine learning, and database mining techniques to collate information from public and proprietary genomic repositories. Recent advances in computational biology have demonstrated that automated annotation systems can significantly improve the accuracy of variant classification by minimizing human error and ensuring consistency in data interpretation (Adeniran, 2024). Moreover, the tool will be designed with a user-friendly interface to make it accessible to clinicians and researchers with varying levels of computational expertise. The integration of real-time data updates and cross-referencing with clinical databases is expected to enhance the tool’s utility in identifying pathogenic variants, benign mutations, and variants of uncertain significance. In addition, the study addresses challenges related to data heterogeneity and the scalability of annotation pipelines, ensuring that the tool remains robust as the volume of genomic data continues to increase. Overall, the development of an automated genomic variant annotation tool promises to bridge the gap between raw sequencing data and actionable clinical insights, ultimately supporting improved patient outcomes and accelerating genetic research (Chukwu, 2025).
Statement of the Problem :
The manual annotation of genomic variants is a labor-intensive and error-prone process that limits the pace of genetic research and clinical diagnostics. Existing tools often require significant human intervention to accurately classify variants, leading to delays and potential misinterpretations (Okeke, 2023). In many instances, the lack of standardized annotation protocols results in inconsistent data outputs, which can undermine clinical decision-making. Furthermore, the exponential growth in sequencing data has outpaced the capacity of traditional annotation methods, necessitating the development of automated solutions. Data heterogeneity, inconsistencies in variant nomenclature, and the integration of diverse data sources present additional challenges that impede the efficient annotation of variants. There is also a critical need for a tool that can not only annotate variants rapidly but also update annotations in real-time as new genomic information becomes available. The current study aims to address these challenges by developing an automated tool that integrates multiple bioinformatics resources and employs machine learning algorithms to ensure high accuracy and consistency in variant classification. By validating the tool using datasets from Federal University, Wukari, the research will assess its performance in terms of speed, accuracy, and usability. This investigation is crucial for enabling more efficient genomic data interpretation, thereby facilitating the translation of genetic research into clinical practice. Addressing these issues will help to bridge the gap between the vast amounts of generated sequencing data and the need for timely, accurate clinical insights (Ibrahim, 2025).
Objectives of the Study:
-
To design and develop an automated genomic variant annotation tool that integrates multiple data sources.
-

Significance of the Study:
This study is significant as it proposes an automated solution to streamline genomic variant annotation, reducing manual errors and accelerating data interpretation. The tool will enhance clinical diagnostics and genetic research, leading to improved patient care and more efficient research processes (Adeniran, 2024).
Scope and Limitations of the Study:
The study is limited to the design, development, and evaluation of an automated genomic variant annotation tool using data from Federal University, Wukari, Taraba State, and does not extend to therapeutic interventions or long-term clinical outcome studies.
