Genetics and Cancer

Genetic Testing

Genetic testing is done by examining the strand of letters that make up the specific gene of interest, this is called DNA sequencing. The DNA letters that make up the gene will be examined by an automated machine at a specialized laboratory. This machine essentially spell-checks the letters that make up the gene to make sure that they are arranged correctly and that there are no extra or deleted letters. The testing can be done on a small blood sample. This specialized testing is offered to individuals after a genetic counselor has made an individualized risk assessment that indicates a specific gene of interest.
