genetic counselor
(jeh-NEH-tik KOWN-seh-ler)
A health professional who has special training in medical genetics and counseling. Genetic counselors help patients and families who have, or who may be at risk of, a genetic condition. They help patients find out their chances of having a genetic condition or of having a child or other family member with a genetic condition. They also help patients understand their options for genetic testing, including its risks and benefits. After genetic testing is done, genetic counselors help patients understand their genetic test results, including how the results can affect other family members, and provide counseling and support.
