Frequently Asked Questions

What is a genetic disease or disorder?

A genetic disease or disorder is caused by mutations, or changes, in your genes that happen over time. Every cell in your body has thousands of different genes. You inherit two copies of each gene: one from your mother, one from your father. Genes carry all the information that makes you the unique person you are. They determine everything from your eye and hair color to your blood type and whether you’ll be short or tall. And just as your genes can determine if you’ll have a bald spot like your dad or dimples like your mom, they can also determine your chance of getting certain diseases, such as cancer. They can determine if there’s a possibility you may pass on a disease to your child. They can determine if your baby is likely to be born with a genetic condition such as sickle cell disease or cystic fibrosis, or a chromosome problem like Down syndrome.

What is genetic testing?

Genetic testing is used to identify the changes in your genes or your chromosomes that could lead to a genetic or inherited condition. Genetic conditions can affect your health and the health of your children.

Who may be offered genetic tests?

If your personal or family history suggests that genetic testing would be helpful, your health care provider may refer you to a genetic counselor or geneticist for evaluation and to discuss if genetic tests are right for you.  There are also some screening tests that are ordered during pregnancy and after delivery of the baby.

How are genetic tests performed?

Testing is usually done with a small sample of blood, or other body tissue.

When and how will I get results?

The time it takes to get results varies depending on the test. Your genetic or other health care provider will contact you with your results.

What is a genetic counselor?

Genetic counselors are health care professionals with specialized graduate degrees and experience in the areas of medical genetics and counseling. Our genetic counselors are certified by the American Board of Genetic Counselors and are licensed in California.
