A frontier company in medical genetics research DNA Link is currently in collaboration with Korea’s most renowned clinical research specialists studying genetic effects of various diseases including diabetes, cardiovascular disease, cancer, atopy, and digestive diseases. Recent advancements in genomic research technology have enabled rapid analysis of whole genomes. Our current research projects utilize this technology to identify relationships between diseases and genomic content. In the past, genetic disease studies were conducted using a finite set of candidate genes as targets for research. While the results were valuable, the success of this approach was limited because diseases can depend on multiple factors, genetic and environmental. Modern genetic research methodologies take a more extended approach, considering the entire human genome to search for potential disease markers. In addition to identifying disease-related genes, DNA Link is working to develop disease diagnostic systems as well as personalized treatment methods. Using DNA Chip and Next Generation Sequencing technologies, we are currently developing cancer diagnostic systems by identifying common variants in DNA copy numbers for various cancers including lung cancer and breast cancer
