Gene panel testing is a type of genetic testing that sequences the entire genome of a patient accused of mediating a disease based on a genetic abnormality or genetically inherited, such as cancer or cardiovascular disease. Pharmacogenetics, congenital disease detection, and cancer risk assessment are just a few of the applications of gene panels. Gene panel detects and predicts rare genetic alterations that spread diseases such as Lynch syndrome (hereditary non-polyposis colorectal cancer) that are at higher risk than other cancers such as stomach, ovarian and colon cancers It is a useful diagnostic tool for Targeted gene panels can be used to look for specific genetic variants associated with the disease or phenotypic attribute being studied or studied. Recent breakthroughs in gene sequencing have led to the development of user-specific gene panels.
