The Division of Clinical Genetics at Joe DiMaggio Children's Hospital evaluates and diagnoses genetic conditions in both children and adults and provides appropriate treatment or referrals based on each patient's needs. Genetic testing is a very complex process, and patients should be evaluated by a clinical geneticist who understands how genetic testing works and how to interpret the test results.

Our team of genetic professionals includes:

  • Board-certified clinical geneticists
  • Board-certified genetic counselor
  • Registered dietitian specializing in metabolic conditions

Our team works together to provide genetic evaluation, counseling and health management services to patients of all ages – from pregnant women and newborns to seniors.

Genetic Counseling

The results of genetic testing can seem overwhelming and confusing. Our board-certified genetic counselor explains genetic testing results in a way that is easy to understand. The counselor will discuss recurrence risks and inheritance patterns, which can be important for families considering future pregnancies. 
You will likely see a genetic counselor if you have:
  • A personal or family history of a genetic disorder
  • A child with a genetic disorder or birth defect

Why Would You Visit Genetics?

There are many reasons a child or adult may be referred to a genetics clinic. Often genetic testing can help identify a cause for the following conditions:
  • Developmental delay/intellectual disability
  • Autism spectrum disorders
  • Birth defects
  • Neuromuscular disorders
  • Cardiomyopathies
  • Failure to thrive or growth retardation
  • Obesity
  • Hearing loss
  • Seizures
  • Marfan syndrome and other connective tissue disorders
  • Prader-Willi syndrome and Angelman syndrome
  • Inborn errors of metabolism

In other cases, patients see us after another doctor has ordered genetic testing that has confirmed one of the following:

  • Chromosomal anomalies (i.e. Down syndrome, Turner syndrome, trisomy 13, trisomy 18)
  • Microdeletion/microduplication syndromes
  • Positive results on a single gene or panel test
  • Variants of uncertain significance found on chromosomal or gene testing that need further interpretation

Other reasons to be referred to a genetics clinic include:

  • Prenatal drug or alcohol exposure
  • Family history of a genetic condition
  • Preconception (family planning)

Medical Genetics Frequently Asked Questions

What happens at a genetics appointment?

The geneticist and/or genetic counselor will get to know you and your family. They will ask lots of questions about your medical history and family history. The geneticist will complete a physical exam, similar to what your primary care/pediatrician does. After that, they will have a discussion with you about if any genetic testing is recommended and why they are recommending that test. 

What is genetic counseling?

Genetic counseling involves analyzing medical history and family history to determine if any genetic testing might be right for you or a family member. The genetic testing recommended will be explained in detail and you will have the opportunity to ask questions and make an informed decision. When the results are available, genetic counseling involves explaining how this result may impact your future health or the health of your future family members. Inheritance patterns will be explained, and appropriate support and resources will be provided to you if needed. Genetic counseling can be provided by a genetic counselor or a geneticist.

If I come for a genetics appointment do I have to pursue genetic testing?

No. Genetic testing is a personal decision. Our expert team is here to guide you in making recommendations and make sure you understand all of your options. The decision to pursue genetic testing is yours. In some cases, genetic testing may not be recommended if there is not a good genetic test available for your symptoms. 

Does everyone receive a definitive diagnosis?

Unfortunately, not everyone has an identifiable genetic condition that we are able to diagnose. There are many types of genetic tests available, so the chances of finding an answer for those who want one have certainly increased over the years. We also have options to refer patients who are undiagnosed to research studies that can help to try to find a diagnosis.

Is the geneticist going to try to do research on me/my child?

No. The geneticist is there to evaluate, diagnose, and if possible, treat your child’s symptoms. Sometimes research options are available, which will be discussed in detail if there is one appropriate for your family member’s condition. There is absolutely no obligation to participate in research studies if you are not interested.
