The Prenatal Diagnostic Center at UCSF provides comprehensive counseling, screening and diagnostic testing for fetal defects. The decision to make use of these services in unique for each woman and her partner. We are committed to providing the information and support that patients need to make the choices that are right for them.
We are also committed to providing the highest quality care and service. We offer the most advanced technology and procedures, including NT (nuchal translucency) screening. Our practitioners have a wealth of expertise and experience, having performed more than 40,000 amniocentesis and 15,000 chorionic villus sampling (CVS) procedures over the past 35 years.
In addition to providing the most advanced testing available today, the Prenatal Diagnostic Center is working to develop new and less invasive methods for the screening and diagnosis of genetic and chromosomal disorders. Research studies are available for women interested in participating.
The center has three satellite clinics in Northern California, in addition to our main San Francisco office.

Genetic Carrier Screening:
Depending on your family history, ethnicity and heritage, your developing baby may be at risk for one of these other genetic conditions:
Sickle Cell Disease — This condition is most common in persons of African-American, African, Mediterranean, Hispanic and South American ancestry, with the carrier risk ranging from 1/10 to 1/40, depending on your ethnic background. Sickle cell disease is caused by a variant hemoglobin that changes the shape of the red blood cells. This causes anemia, severe pain, a tendency toward infection and other serious health problems. Frequent blood transfusions, infection-preventing antibiotics and bone marrow transplant are available treatments. UCSF doctors were the first to develop a prenatal test for sickle cell anemia.
Tay Sachs Disease — People of both Ashkenazi Jewish and French Canadian ancestry have the greatest chance of being carriers of Tay Sachs disease, about 1/30 versus 1/250 in the general population. The disease results from a build up of certain substances in the brain, and is fatal in early childhood. There is presently no effective treatment for Tay Sachs disease.
Thalassemia — Individuals of Mediterranean, Southeast Asian and African ancestry have the greatest chance — 1 in 3 and 1 in 30, respectively — of being carriers for thalassemia. In general, this group of blood disorders affects a person's ability to produce hemoglobins, the protein in our blood that carries oxygen and nutrients to all parts of the body. In severe cases, children with thalassemia may not survive. Others have anemia, bone growth problems and liver and spleen involvement. Blood transfusions may be needed for treatment. UCSF doctors were the first to develop a prenatal test for thalassemia.
Some genetic disorders are more common in certain ethnic groups. People who carry genes for these disorders may not have symptoms. However, if both parents are carriers of the same abnormal gene, the chance of having an affected child is 1 in 4, or 25 percent, for each pregnancy. A special blood test, called a carrier test, may be able to tell if you carry such a trait.
