Center for Genetic Counseling

Evaluating Your Risk for Genetic Conditions

Are you concerned that your family history of diseases and conditions may put you or your children at higher risk for those diseases or other conditions? Our genetic counselors can help. They are among the world’s experts in evaluating family history to assess disease risk. 

Services we provide include:

  • Gathering family history to assess disease risk
  • Helping you determine whether genetic testing is appropriate
  • Outlining the risks and benefits of testing
  • Reviewing genetic test results with you
  • Discussing what genetic test results mean for you and your family

Our Team

Each of our genetic counselors is board certified by the American Board of Genetic Counseling. Our genetic counselors work with teams of experts at Johns Hopkins to conduct research on genetic conditions with the aim of improving the genetic counseling process and intervention, informed consent, and personal and family coping and adaptation to disease. They also work to educate other medical professionals, the next generation of genetic counselors and the public by participating in support groups and advocacy organizations, professional associations, and supervising and teaching students at all educational levels at Johns Hopkins and elsewhere.

In addition to the genetic counseling team in the Department of Genetic Medicine, we also work closely with genetic counseling colleagues across the Johns Hopkins Medicine system, including those in cardiogenetics, preconception and prenatal genetics, and cancer genetics, to ensure that you and your family receive expert, coordinated care.
