Assist. Lec. Ali Hussein Shakir Medical genetics has undergone rapid development in recent years and has become an important field in advancing healthcare and transitioning toward precision and personalized medicine. Technologies such as Next-Generation Sequencing (NGS), pharmacogenomics, and gene editing using CRISPR-Cas9 have contributed to improving the diagnosis of certain diseases, supporting treatment selection, and reducing some adverse drug effects. Radiogenomics has also emerged as an interdisciplinary field that integrates genetic information with medical imaging techniques such as CT, MRI, and PET. It aims to investigate the relationship between the molecular and genetic characteristics of diseases and features extracted from medical images. This integration provides new opportunities for improving disease characterization, particularly in oncology, and supporting the development of more accurate healthcare models. Despite these advances, the application of medical genetics faces challenges related to genetic data privacy, interpretation of results, technology costs, and the availability of specialized personnel and infrastructure. Therefore, effective implementation of these applications requires multidisciplinary collaboration among genetics, radiology, laboratory medicine, and bioinformatics specialists.

Introduction Advances in the study of the human genome and DNA analysis technologies have brought significant changes to the diagnosis, prevention, and treatment of diseases. Precision medicine relies on integrating genetic and molecular information with clinical data to provide healthcare that is more appropriate to each patient's individual characteristics. Medical genetics has become increasingly connected with various healthcare disciplines, including radiological technologies, through the emergence of Radiogenomics, which investigates the relationship between the genetic and molecular characteristics of diseases and information obtained from medical images. 2. Major Applications of Medical Genetics One of the most important modern applications is Next-Generation Sequencing (NGS), which enables the analysis of large amounts of genetic information and supports the diagnosis of certain genetic diseases and complex conditions. Pharmacogenomics also contributes to studying the effect of genetic variations on patients' responses to medications, which may help improve treatment selection and reduce certain adverse drug reactions. CRISPR-Cas9 represents an advanced gene-editing technology that has opened new research and therapeutic opportunities for certain genetically based diseases, while safety and long-term efficacy continue to be investigated. In radiological technologies, Radiogenomics represents an important research direction that integrates medical image analysis with genomic information. It can be used to study tumors and correlate imaging characteristics with certain molecular and genetic indicators, thereby supporting the development of personalized diagnosis and treatment. 3. The Role of Genetics in Improving Healthcare Quality Applications of medical genetics can contribute to: Improving the accuracy of diagnosing certain genetic and rare diseases. Supporting early diagnosis in appropriate clinical conditions. Assisting in the selection of certain targeted therapies. Reducing some adverse drug effects through pharmacogenomics. Developing more integrated approaches to analyzing medical images and genetic data. Supporting the transition toward precision medicine and personalized healthcare. 4. Challenges The major challenges include protecting the privacy of genetic data, interpreting variants of uncertain significance, the high costs of advanced technologies, and the need for specialized personnel and advanced infrastructure. Ensuring equitable access to genomic technologies also represents an important challenge for healthcare systems. 5. Conclusion Modern medical genetics represents a promising field for improving healthcare quality by enhancing diagnosis, supporting treatment selection, and promoting the concept of precision medicine. Furthermore, the integration of genetics with radiological technologies, particularly through Radiogenomics and Radiomics, opens important research opportunities for the field of radiological technologies. Achieving the full potential of these developments requires strengthening collaboration among medical and technological disciplines while adhering to scientific and ethical standards and protecting patients' privacy.
