The complete DNA sequence of the human genome was obtained using next-generation sequencing technologies, providing a comprehensive map of three billion base pairs. Thousands of single nucleotide polymorphisms (SNPs) were identified across the genome, contributing to human genetic diversity. Numerous copy number variations (CNVs) and structural variants, such as deletions, duplications, and inversions, were discovered, influencing genetic traits and disease susceptibility. Genome-wide association studies (GWAS) revealed genetic variants associated with various complex diseases, including cancer, diabetes, cardiovascular disorders, and neurological conditions. Specific SNPs were linked to disease risk and provided insights into disease etiology and potential therapeutic targets. Genetic variations affecting drug metabolism and response were identified, paving the way for pharmacogenomics-based personalized medicine. Certain genetic variants were associated with drug efficacy and adverse drug reactions, enabling tailored drug prescriptions based on individual genetic profiles. Genetic markers and biomarkers were identified for specific diseases, enabling the development of genomics-based diagnostic tests for early disease detection and risk assessment. Diagnostic panels incorporating genetic variants improved disease diagnosis and prognostication (Fig.1). Genetic profiling of individuals allowed for precise patient stratification, guiding treatment decisions for personalized therapeutic interventions. Targeted therapies based on genomic profiles demonstrated improved treatment outcomes and reduced side effects. Population-based studies provided insights into human migration patterns and ancestry, shedding light on human evolutionary history (Tab.1.). Genomic data were used to study population-specific genetic variations and potential health disparities. Ethical considerations surrounding the use of genomic data in healthcare and research were addressed, including data privacy, informed consent, and equitable access to genomic information. Strategies for integrating genomics into healthcare while safeguarding individual rights and ensuring responsible data sharing were explored. Genomic information was utilized to identify individuals at high risk of developing certain diseases, enabling early interventions and preventive measures. Public health strategies incorporating genomic data contributed to disease prevention and improved population health.
