Pre-Implantation Genetic Diagnosis of Embyros Provide "Gene Security" to Sacramento Area IVF Patients

In recent years, genetic testing has made the leap from science fiction to science present. While many older moms-to-be worry about disorders such as Down Syndrome, they are not the only women who can benefit from advanced genetic testing. Couples of any age who have miscarried frequently may gain new insight into their best pregnancy options by combining in-vitro fertilization (IVF) with a 24 gene screening test. At California IVF: Davis Fertility Center, Inc., we are proud to be the greater Sacramento area partner for Gene Security Network, an innovative genetic testing company based in Redwood City, CA. This partnership allows us to provide patients and referring doctors with the cutting edge technology necessary to make informed decisions about the best chances for pregnancy.

Performed in the three to five day window between egg fertilization and embryo implantation, a twenty-four gene pre-implantation genetic diagnosis (PGD24) is a battery of tests that looks at twenty three pairs of chromosomes along with the X/Y gender selecting pair. The result is a chromosome-level glimpse into the viability of a patient’s developing embryos. Ruling out the implantation of embryos with known genetic disorders is the primary reason for this test. Although it is not recommended to perform PGD24 for gender selection alone, this is one potential benefit for couples who are concerned about potential genetic disorders, already have children and wish to balance out their current families by favoring the selection of healthy embryos of a certain sex.

On its website, Gene Security Network lists the following reasons for combining IVF and PGD24 testing:
- the female partner is 35 years of age or older
- the couple has had recurrent miscarriages of unknown cause
- a previous child or pregnancy has had a chromosome abnormality
- the couple is concerned about having a child with a chromosome abnormality
- the couple has had a previous, unsuccessful IVF cycle
- one member of the couple carries a balanced chromosome translocation or inversion
- the couple is at risk of having a child with an inherited single gene genetic disease
