Genetic counseling is one of the many services offered in the Maternal Fetal Diagnostic Center. Patients are educated about their prenatal testing options, as well as their risk of having a child with a birth defect or genetic disease. Our genetic counselors are specialty trained, licensed professionals who help determine what tests are appropriate for each family. When testing is complete, our counselors clearly explain the results and provide education and counseling if necessary.

Patients are referred for genetic counseling for a variety of indications including the following:

  • First trimester screening
  • Abnormal maternal serum screening
  • Advanced maternal age
  • Abnormal finding by ultrasound examination
  • Recurrent miscarriage
  • Family history of a birth defect or genetic disease

Preconceptional counseling is also offered.

When to Seek Genetic Counseling

Genetic counseling is a professional assessment of a person's or couple's risk factors regarding their family history, medical history, and/or pregnancy history. The goal of genetic counseling is not only to assess risk, but also to explain the cause and inheritance of a disorder, the availability of testing, the prognosis, medical management, and treatment. Genetic counseling sessions typically last one hour or longer, depending on the complexity of the case. Genetic counseling can be provided by a geneticist, by a doctor with special training and Board Certification in genetics, or by genetic counselors. Genetic counselors have a minimum of a master's degree in genetic counseling or a related field, which includes extensive training in human clinical genetics and counseling. The American Board of Genetic Counseling offers a certification examination for this discipline every year.

The following lists potential reasons to seek a referral for genetic counseling and/or genetic evaluation with a genetic doctor.

    • Hearing or visual impairments

    • Learning disabilities

    • Psychiatric disorders

    • Cancers

    • Multiple pregnancy losses, such as miscarriages, stillbirths, or infant deaths

    • Other disorders which could be considered genetic

  • Either parent with an autosomal dominant disorder, or any disorder seen in several generations

  • Both parents are carriers for an autosomal recessive disorder, diagnosed either by the birth of an affected child or by carrier screening

  • Either parent is a known carrier of a balanced chromosome abnormality

Pregnancy factors:

  • Maternal age 35 years or greater at delivery

  • Advanced paternal age at the time of conception

  • Infertility cases where either parent is suspected of having a chromosome abnormality

  • Couples requiring assisted reproductive techniques to achieve a pregnancy, or individuals donating eggs or sperm for those purposes

Other factors:

  • People in specific ethnic groups or geographic areas with a higher incidence of certain disorders, such as Tay-Sachs disease, sickle cell disease, or thalassemias
