Early clinics have long tested for rare single-gene mutations (e.g. MYOC, OPTN) in families with juvenile or early-onset glaucoma (). But such...
Genomics is the study of an organism’s complete set of DNA, including all of its genes and how they interact. Instead of focusing on one gene at a time, genomics looks at patterns across the whole genome to understand how genetic differences influence health, development, and disease. Scientists use tools like DNA sequencing to read those patterns and find genetic variations that may increase or decrease disease risk. This field helps explain why people respond differently to the same drug, why some diseases run in families, and how organisms evolve. Genomics matters because it provides a powerful way to discover the biological causes of conditions and to develop new diagnostics, treatments, and prevention strategies. It also supports public health efforts by identifying population-level genetic trends and potential targets for vaccines or therapies. Understanding genomics requires careful interpretation and large data sets, and it raises important questions about privacy, consent, and equitable access to benefits. When used responsibly, genomic knowledge can guide better medical care and help scientists build more effective medicines.
