Genetic testing is a cornerstone of precision medicine. In pediatrics, genetic testing can help identify hereditary conditions early, allowing for timely interventions. For instance, understanding a child's genetic predisposition to certain diseases like cystic fibrosis or congenital heart defects can guide treatment plans and lifestyle adjustments. Moreover, pharmacogenomics—the study of how genes affect a person's response to drugs—can help in selecting the most effective medications with the least side effects for young patients.
