Genomic testing is a process by which clinicians study the activity and interaction of genes within the human body. The Weill Cornell Medicine Clinical Genomics Laboratory facilitates genomic testing assessments of mutations in roughly 22,000 different human genes. These assessments provide clinically actionable diagnoses for personalized patient care. Our highly trained professional staff members use genomic tests to identify alterations in genes that cause cancer to grow and spread within the body, determine the genetic drivers of these mutations and provide insights for disease treatment.
