Tamar Goldwaser, MD






At MFM Associates, we have a skilled OBGYN- Medical Geneticist to assist patients with some of the most complicated issues facing expectant parents today. Dr. Tamar Goldwaser helps patients better understand their genetic testing options, genetic test results and how these results can impact their health.  She helps families understand the meaning and limitations of genetic testing. One of her many skills is her ability to listen to the patient’s story, bring forward her values and priorities, and use these factors to provide very personalized guidance and advice.

What Does a Geneticist Do?

A geneticist’s role is to review your genetics by gathering information on your family health history and results from DNA testing. With this information, they can then help you make informed decisions about your health care, including reproductive health and fertility options. Often, services with a geneticist are considered genetic counseling, meaning that they will counsel you to help you best understand any testing results and your best options. Many geneticists work together with genetic counselors.

Prenatal and Preconception Genetic Screening

During preconception and prenatal genetic consultations, Dr. Goldwaser can help you understand the range of possible outcomes if your child inherits a genetic condition or interpret complex test results from an amniocentesis.

Antepartum Genetic Counseling for Complex Genetic Cases

Antepartum genetic counseling occurs during pregnancy for patients who have particularly complex genetic cases.

Consultation Prior to IVF

Genetic consultation before IVF helps parents understand how assisted reproductive technologies can be useful. Dr. Goldwaser can explain the various genetic testing technologies to patients who are preparing for IVF.

Before implantation in an IVF cycle, an embryo’s genetics can be tested to screen for conditions that can cause issues like implantation failure, miscarriage, and birth defects. This testing is called pre-implantation genetic testing.

Pre-implantation genetic testing (PGT) can be used to screen embryos for chromosome imbalances and for other genetic conditions. Dr. Goldwaser can consult with patients to discuss the implications of using an embryo with abnormal or mosaic PGT results. Patients can learn about their options for testing embryos for a specific genetic condition that the parents carry before they are implanted.

Making an informed decision regarding IVF and PGT helps to give parents the best chances for a healthy outcome

Carrier Screening

Genetic carrier screening involves testing your DNA through a blood test to see if you and your partner are carriers for common inherited diseases.


Performed for expectant mothers between 16 and 22 weeks, an amniocentesis evaluates a sample of amniotic fluid to check for chromosomal and single-gene abnormalities that cause conditions such as Down syndrome or cystic fibrosis. Amniocentesis is available to any woman of any age. The results from an amniocentesis are diagnostic (definitive).

Chorionic Villus Sampling

Chorionic Villus Sampling, or CVS, is performed for expectant mothers between 11 and 14 weeks gestation. A CVS is a biopsy of the placenta, and involves testing a sample of tissue from the placenta to check for chromosomal and single-gene abnormalities.  Chorionic villus sampling is available to any woman of any age. The results from a CVS are diagnostic (definitive).

Who Should See a Geneticist?

Many patients can benefit from a consultation with a geneticist. Those with family histories of genetic conditions are especially encouraged to meet with a geneticist, ideally before but also during a pregnancy.  Patients with a history of a pregnancy with any birth defects or genetic abnormalities can also benefit from a preconception genetic consultation. Patients who are concerned about their risk to develop cancers due to a family history of cancer or due to a known familial genetic mutation/variant such as BRCA1, BRCA2 or Lynch syndrome, should seek out the guidance of a geneticist.

Outside of these higher risk factors, virtually any patient can benefit from genetic counseling or screening if they are considering getting pregnant. A genetic counselor can evaluate your best options.
