Whole genome sequencing (WGS) is a comprehensive technique that analyzes an individual's entire genome, including both coding and non-coding regions of DNA. Unlike whole exome sequencing, which only targets protein-coding regions, WGS provides a complete view of the genetic blueprint. This method can identify genetic mutations, structural variants, and other changes that may contribute to diseases or traits. WGS is particularly useful for understanding complex genetic conditions and uncovering rare or previously unknown mutations. It involves high-throughput sequencing technologies that generate vast amounts of data for analysis. WGS is increasingly used in personalized medicine, genetic counseling, and research into genetic disorders. The information from WGS can guide treatment plans, risk assessments, and family planning decisions.
