Genetic Disorders: Molecular Mechanisms, Diagnostic Evolution, Precision Therapeutics and Future Directions Description Genetic Disorders: Molecular Mechanisms, Diagnostic Evolution, Precision Therapeutics and Future Directions is a comprehensive narrative review examining the current understanding and rapidly evolving landscape of genetic disorders. The review integrates advances in molecular genetics, genomic diagnostics, precision medicine, and emerging therapeutic strategies to provide a broad perspective on the diagnosis and management of genetic diseases. The review explores the molecular mechanisms underlying genetic disorders, including pathogenic genetic variants, mutations, genomic alterations, gene regulation, and disrupted molecular pathways involved in disease development and progression. It further examines the evolution of genetic diagnosis from conventional approaches toward advanced genomic technologies, including next-generation sequencing (NGS), whole-exome sequencing (WES), whole-genome sequencing (WGS), and molecular diagnostic approaches. A major focus of this review is the development of precision therapeutics and personalized medicine. Emerging approaches such as gene therapy, genome editing, RNA-based therapies, targeted molecular treatments, and genotype-guided therapeutic strategies are discussed in the context of their potential to transform the management of genetic disorders. The review also addresses important challenges in genomic medicine, including variant interpretation, genetic counseling, ethical considerations, accessibility of advanced diagnostic technologies, clinical implementation, and the integration of genomic data into routine healthcare. Finally, the article highlights future directions in genetic medicine, including the potential contributions of artificial intelligence, bioinformatics, multi-omics technologies, genomic data analysis, and precision healthcare. These developments may facilitate earlier diagnosis, improved disease classification, individualized treatment selection, and better clinical outcomes. Overall, this narrative review provides an integrated overview of the transition from traditional genetic diagnosis and management toward genomics-driven, mechanism-based, and precision therapeutic approaches, while identifying key opportunities and challenges for future research and clinical practice. Keywords:Genetic Disorders; Molecular Genetics; Genetic Mutations; Genomic Medicine; Molecular Mechanisms; Genetic Diagnosis; Next-Generation Sequencing; Whole-Exome Sequencing; Whole-Genome Sequencing; Precision Medicine; Precision Therapeutics; Gene Therapy; Genome Editing; RNA-Based Therapy; Personalized Medicine; Bioinformatics; Artificial Intelligence; Genomic Technologies.

Description Thalassemia as a Genetic Disorder: From β-Globin Mutation to Precision Prevention and Gene-Based Therapy is an evidence-informed international review that provides a comprehensive overview of thalassemia as an inherited genetic disorder, with particular emphasis on the molecular basis of disease, β-globin gene mutations, genotype–phenotype relationships, disease mechanisms, clinical manifestations, diagnosis, prevention, and emerging therapeutic strategies. The manuscript examines how pathogenic variants affecting β-globin synthesis contribute to ineffective erythropoiesis, chronic anemia, iron overload, and the major clinical complications associated with thalassemia. It also discusses advances in molecular diagnostics, carrier screening, genetic counseling, prenatal and preimplantation genetic testing, and population-based prevention strategies. A major focus of this review is the transition from conventional supportive management toward precision medicine and gene-based therapies. Recent developments in hematopoietic stem-cell transplantation, genome editing, gene addition, and other molecularly targeted approaches are considered in the context of their potential to modify the underlying genetic cause of disease. By integrating genetic, clinical, preventive, and therapeutic perspectives, this review aims to provide researchers, physicians, genetic counselors, students, and public-health professionals with an accessible evidence-informed synthesis of current knowledge and emerging directions in thalassemia prevention and treatment. Keywords: Thalassemia; β-thalassemia; α-thalassemia; β-globin gene; HBB gene; genetic mutations; hemoglobin disorders; inherited blood disorders; anemia; ineffective erythropoiesis; iron overload; genetic screening; carrier screening; genetic counseling; prenatal diagnosis; preimplantation genetic testing; molecular diagnostics; precision medicine; gene therapy; gene editing; genome editing; CRISPR; hematopoietic stem-cell transplantation; gene-based therapy; transfusion-dependent thalassemia; thalassemia prevention; personalized medicine.
