Traditionally, the high costs and enormous expenditure of time associated with DNA sequencing has allowed an examination of only a few genes at a time for a given patient. Using this approach, the causative gene mutation can be very difficult to find in clinically diagnosed patients with a suspected genetic disease. Diagnostic gene panels enable accurate diagnosis and optimal treatment for patients, without the limitations of traditional DNA sequencing and analysis. This approach takes advantage of next-generation sequencing technologies, which facilitate the process of simultaneously analyzing all known genes associated with a certain disease. This represents a significant advantage in the diagnosis of genetic diseases.
