Most genetic diseases that run in a family are caused by changes within individual genes and not missing or extra chromosome material. Anora is not able to test for specific single gene disorders. You should discuss your family history with your doctor or a local genetic counselor to find out if other types of genetic testing are available to better understand your family history. One exception to this is chromosomal rearrangements, which can sometimes run in a family. It is estimated that about 1 in 500 people have the correct amount of genetic information, but it is arranged in a different way (called a balanced translocation or inversion). A carrier of a balanced rearrangement is healthy, but may be at increased risk for miscarriage or children with chromosomal abnormalities. Anora can provide helpful information that indicates a parent may be a balanced translocation or inversion carrier.
